Opening on June 16, 2016, it replaced Walt Disney World ’s Cinderella Castle as the tallest castle in all of the related Disney theme parks. The look of Enchanted Storybook Castle was inspired by many other Disney Castles, including Cinderella Castle and Sleeping Beauty Castle. Similarly to the Castle of Magical Dreams in Hong Kong Disneyland, it represents all of
216-606: A drawbridge , although these were often replaced by stone bridges. The site of the 13th-century Caerphilly Castle in Wales covers over 30 acres (12 ha) and the water defences, created by flooding the valley to the south of the castle, are some of the largest in Western Europe. Battlements were most often found surmounting curtain walls and the tops of gatehouses, and comprised several elements: crenellations , hoardings , machicolations , and loopholes . Crenellation

The Military Revolution thesis originally proposed by Michael Roberts in 1955, as he focused on Sweden (1560–1660) searching for major changes in the European way of war caused by
432-471: A Roman fort or Byzantine tetrapyrgia which were square in plan and had square towers at each corner that did not project much beyond the curtain wall. The keep of these Crusader castles would have had a square plan and generally be undecorated. While castles were used to hold a site and control movement of armies, in the Holy Land some key strategic positions were left unfortified. Castle architecture in
540-462: A barbican was not just to provide another line of defence but also to dictate the only approach to the gate. A moat was a ditch surrounding a castle – or dividing one part of a castle from another – and could be either dry or filled with water. Its purpose often had a defensive purpose, preventing siege towers from reaching walls making mining harder, but could also be ornamental. Water moats were found in low-lying areas and were usually crossed by
648-438: A central keep . In the late 12th and early 13th centuries, a scientific approach to castle defence emerged. This led to the proliferation of towers, with an emphasis on flanking fire . Many new castles were polygonal or relied on concentric defence – several stages of defence within each other that could all function at the same time to maximise the castle's firepower. These changes in defence have been attributed to
756-529: A combined Florentine and French army. With the original medieval fortifications beginning to crumble to French cannon fire, the Pisans constructed an earthen rampart behind the threatened sector. It was discovered that the sloping earthen rampart could be defended against escalade and was also much more resistant to cannon fire than the curtain wall it had replaced. The second siege was that of Padua in 1509. A monk engineer named Fra Giocondo , trusted with
864-574: A common origin, dealt with a particular mode of warfare, and exchanged influences. In different areas of the world, analogous structures shared features of fortification and other defining characteristics associated with the concept of a castle, though they originated in different periods and circumstances and experienced differing evolutions and influences. For example, shiro in Japan, described as castles by historian Stephen Turnbull , underwent "a completely different developmental history, were built in
972-480: A completely different way and were designed to withstand attacks of a completely different nature". While European castles built from the late 12th and early 13th century onwards were generally stone, shiro were predominantly timber buildings into the 16th century. By the 16th century, when Japanese and European cultures met, fortification in Europe had moved beyond castles and relied on innovations such as
1080-648: A confined space and unable to retaliate. It is a popular myth that murder holes – openings in the ceiling of the gateway passage – were used to pour boiling oil or molten lead on attackers; the price of oil and lead and the distance of the gatehouse from fires meant that this was impractical. This method was, however, a common practice in Middle Eastern and Mediterranean castles and fortifications, where such resources were abundant. They were most likely used to drop objects on attackers, or to allow water to be poured on fires to extinguish them. Provision
1188-471: A ditch was dug in front of them. The earth used from the excavation was piled behind the walls to create a solid structure. While purpose-built fortifications would often have a brick fascia because of the material's ability to absorb the shock of artillery fire, many improvised defences cut costs by leaving this stage out and instead opting for more earth. Improvisation could also consist of lowering medieval round towers and infilling them with earth to strengthen

#17327725594781296-532: A formative influence on the patterning of the Renaissance ideal city : "The Renaissance was hypnotized by one city type which for a century and a half—from Filarete to Scamozzi—was impressed upon all utopian schemes: this is the star-shaped city". In the nineteenth century, the development of the explosive shell changed the nature of defensive fortifications. Elvas , in Portugal is considered by some to be
1404-413: A fortification such as a city wall . The great hall was a large, decorated room where a lord received his guests. The hall represented the prestige, authority, and richness of the lord. Events such as feasts, banquets, social or ceremonial gatherings, meetings of the military council, and judicial trials were held in the great hall. Sometimes the great hall existed as a separate building, in that case, it
1512-609: A long time in a constant state of alert"; elsewhere the lord's wife presided over a separate residence ( domus , aula or mansio in Latin) close to the keep, and the donjon was a barracks and headquarters. Gradually, the two functions merged into the same building, and the highest residential storeys had large windows; as a result for many structures, it is difficult to find an appropriate term. The massive internal spaces seen in many surviving donjons can be misleading; they would have been divided into several rooms by light partitions, as in
1620-435: A lord's home or hall was fire as it was usually a wooden structure. To protect against this, and keep other threats at bay, there were several courses of action available: create encircling earthworks to keep an enemy at a distance; build the hall in stone; or raise it up on an artificial mound, known as a motte, to present an obstacle to attackers. While the concept of ditches , ramparts , and stone walls as defensive measures
1728-542: A massive scale, utilising stone, wood, iron and earth in their construction. The Romans encountered fortified settlements such as hill forts and oppida when expanding their territory into northern Europe. Their defences were often effective, and were only overcome by the extensive use of siege engines and other siege warfare techniques, such as at the Battle of Alesia . The Romans' own fortifications ( castra ) varied from simple temporary earthworks thrown up by armies on
1836-494: A mixture of castle technology from the Crusades , such as concentric fortification , and inspiration from earlier defences, such as Roman forts . Not all the elements of castle architecture were military in nature, so that devices such as moats evolved from their original purpose of defence into symbols of power. Some grand castles had long winding approaches intended to impress and dominate their landscape. Although gunpowder
1944-642: A modern office building. Even in some large castles the great hall was separated only by a partition from the lord's chamber, his bedroom and to some extent his office. Curtain walls were defensive walls enclosing a bailey. They had to be high enough to make scaling the walls with ladders difficult and thick enough to withstand bombardment from siege engines which, from the 15th century onwards, included gunpowder artillery . A typical wall could be 3 m (10 ft) thick and 12 m (39 ft) tall, although sizes varied greatly between castles. To protect them from undermining , curtain walls were sometimes given
2052-666: A month. Eventually it fell, but the Ottoman casualties were very high, and it bought time for the relief force which arrived from Sicily to relieve the rest of the besieged island. The star fort therefore played a crucial and decisive role in the siege. After the fall of Venice to Napoleon, Corfu was occupied in 1797 by the French republican armies. The now ancient fortifications were still of some value at this point. A Russian–Ottoman–English alliance led at sea by Admiral Ushakov and with troops sent by Ali Pasha retook Corfu in 1799 after
2160-539: A number of words in other languages also derive from castellum . The word castle was introduced into English shortly before the Norman Conquest of 1066 to denote this type of building, which was then new to England. In its simplest terms, the definition of a castle accepted amongst academics is "a private fortified residence". This contrasts with earlier fortifications, such as Anglo-Saxon burhs and walled cities such as Constantinople and Antioch in
2268-498: A range of purposes, the most important of which were military, administrative, and domestic. As well as defensive structures, castles were also offensive tools which could be used as a base of operations in enemy territory. Castles were established by Norman invaders of England for both defensive purposes and to pacify the country's inhabitants. As William the Conqueror advanced through England, he fortified key positions to secure

#17327725594782376-627: A result there were 4,000 in the country. There are very few castles dated with certainty from the mid-9th century. Converted into a donjon around 950, Château de Doué-la-Fontaine in France is the oldest standing castle in Europe . From 1000 onwards, references to castles in texts such as charters increased greatly. Historians have interpreted this as evidence of a sudden increase in the number of castles in Europe around this time; this has been supported by archaeological investigation which has dated
2484-405: A role in the numerous Mediterranean wars, slowing down the Ottoman expansion. Although Rhodes had been partially upgraded to the new type of fortifications after the 1480 siege, it was still conquered in 1522 ; nevertheless it was a long and bloody siege, and the besieged had no hope of outside relief because the island was close to the Ottoman power base and far from any allies. On the other hand,
2592-476: A scientific design. An example of this approach is Kerak . Although there were no scientific elements to its design, it was almost impregnable, and in 1187 Saladin chose to lay siege to the castle and starve out its garrison rather than risk an assault. During the late 11th and 12th centuries in what is now south-central Turkey the Hospitallers , Teutonic Knights and Templars established themselves in
2700-420: A stone skirt around their bases. Walkways along the tops of the curtain walls allowed defenders to rain missiles on enemies below, and battlements gave them further protection. Curtain walls were studded with towers to allow enfilading fire along the wall. Arrowslits in the walls did not become common in Europe until the 13th century, for fear that they might compromise the wall's strength. The entrance
2808-497: A stronghold and prison but was also a place where a knight or lord could entertain his peers. Over time the aesthetics of the design became more important, as the castle's appearance and size began to reflect the prestige and power of its occupant. Comfortable homes were often fashioned within their fortified walls. Although castles still provided protection from low levels of violence in later periods, eventually they were succeeded by country houses as high-status residences. Castle
2916-424: A wall with openings that allowed objects to be dropped on an enemy at the base of the wall in a similar fashion to hoardings. Arrowslits , also commonly called loopholes, were narrow vertical openings in defensive walls which allowed arrows or crossbow bolts to be fired on attackers. The narrow slits were intended to protect the defender by providing a very small target, but the size of the opening could also impede
3024-400: A wooden door. This led to the elevation of windows to the second storey – to make it harder to throw objects in – and to move the entrance from ground level to the second storey. These features are seen in many surviving castle keeps, which were the more sophisticated version of halls. Castles were not just defensive sites but also enhanced a lord's control over his lands. They allowed
3132-461: Is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield . It was first seen in the mid-fifteenth century in Italy . Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era. The design of the fort is normally a polygon with bastions at the corners of
3240-543: Is a corrupted form of "donjon" and means a dark, unwelcoming prison. Although often the strongest part of a castle and a last place of refuge if the outer defences fell, the keep was not left empty in case of attack but was used as a residence by the lord who owned the castle, or his guests or representatives. At first, this was usual only in England, when after the Norman Conquest of 1066 the "conquerors lived for
3348-462: Is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders . Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion , palace , and villa , whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of

3456-433: Is ancient, raising a motte is a medieval innovation. A bank and ditch enclosure was a simple form of defence, and when found without an associated motte is called a ringwork; when the site was in use for a prolonged period, it was sometimes replaced by a more complex structure or enhanced by the addition of a stone curtain wall. Building the hall in stone did not necessarily make it immune to fire as it still had windows and
3564-527: Is sometimes used as a catch-all term for all kinds of fortifications , and as a result has been misapplied in the technical sense. An example of this is Maiden Castle which, despite the name, is an Iron Age hill fort which had a very different origin and purpose. Although castle has not become a generic term for a manor house (like château in French and Schloss in German), many manor houses contain castle in their name while having few if any of
3672-407: Is the collective name for alternating crenels and merlons : gaps and solid blocks on top of a wall. Hoardings were wooden constructs that projected beyond the wall, allowing defenders to shoot at, or drop objects on, attackers at the base of the wall without having to lean perilously over the crenellations, thereby exposing themselves to retaliatory fire. Machicolations were stone projections on top of
3780-909: The Armenian Kingdom of Cilicia , where they discovered an extensive network of sophisticated fortifications which had a profound impact on the architecture of Crusader castles . Most of the Armenian military sites in Cilicia are characterized by: multiple bailey walls laid with irregular plans to follow the sinuosities of the outcrops; rounded and especially horseshoe-shaped towers; finely-cut often rusticated ashlar facing stones with intricate poured cores; concealed postern gates and complex bent entrances with slot machicolations; embrasured loopholes for archers; barrel, pointed or groined vaults over undercrofts, gates and chapels; and cisterns with elaborate scarped drains. Civilian settlement are often found in
3888-492: The Bayeux Tapestry 's depiction of Château de Dinan . Sometimes a motte covered an older castle or hall, whose rooms became underground storage areas and prisons beneath a new keep. A bailey, also called a ward, was a fortified enclosure. It was a common feature of castles, and most had at least one. The keep on top of the motte was the domicile of the lord in charge of the castle and a bastion of last defence, while
3996-512: The Iron Age . Hillforts in Britain typically used earthworks rather than stone as a building material. Many earthworks survive today, along with evidence of palisades to accompany the ditches. In central and western Europe, oppida emerged in the 2nd century BC; these were densely inhabited fortified settlements, such as the oppidum of Manching . Some oppida walls were built on
4104-480: The Romans . The gatehouse contained a series of defences to make a direct assault more difficult than battering down a simple gate. Typically, there were one or more portcullises – a wooden grille reinforced with metal to block a passage – and arrowslits to allow defenders to harry the enemy. The passage through the gatehouse was lengthened to increase the amount of time an assailant had to spend under fire in
4212-538: The 18th century onwards, there was a renewed interest in castles with the construction of mock castles, part of a Romantic revival of Gothic architecture , but they had no military purpose. The word castle is derived from the Latin word castellum , which is a diminutive of the word castrum , meaning "fortified place". The Old English castel , Occitan castel or chastel , French château , Spanish castillo , Portuguese castelo , Italian castello , and
4320-533: The 9th and 10th centuries after the fall of the Carolingian Empire , which resulted in its territory being divided among individual lords and princes. These nobles built castles to control the area immediately surrounding them and they were both offensive and defensive structures: they provided a base from which raids could be launched as well as offered protection from enemies. Although their military origins are often emphasised in castle studies,

Remains of Roman structures in Western Europe were still standing in many places, some of which had flanking round-towers and entrances between two flanking towers. The castle builders of Western Europe were aware of and influenced by Roman design; late Roman coastal forts on the English " Saxon Shore " were reused and in Spain

Both Christians and Muslims created fortifications, and the character of each was different. Saphadin , the 13th-century ruler of the Saracens, created structures with large rectangular towers that influenced Muslim architecture and were copied again and again, however they had little influence on Crusader castles.

Probably developed in the 12th century, the towers provided flanking fire. They were connected to the castle by removable wooden bridges, so if the towers were captured the rest of the castle was not accessible. When seeking to explain this change in
4860-475: The Italian trace italienne and star forts . A motte was an earthen mound with a flat top. It was often artificial, although sometimes it incorporated a pre-existing feature of the landscape. The excavation of earth to make the mound left a ditch around the motte, called a moat (which could be either wet or dry). Although the motte is commonly associated with the bailey to form a motte-and-bailey castle, this
4968-473: The Middle East; castles were not communal defences but were built and owned by the local feudal lords, either for themselves or for their monarch. Feudalism was the link between a lord and his vassal where, in return for military service and the expectation of loyalty, the lord would grant the vassal land. In the late 20th century, there was a trend to refine the definition of a castle by including
5076-616: The Ottomans failed to take Corfu in 1537 in no small part because of the new fortifications, and several attempts spanning almost two centuries (another major one was in 1716 ) also failed. Two star forts were built by the Order of Saint John on the island of Malta in 1552, Fort Saint Elmo and Fort Saint Michael . Fort Saint Elmo played a critical role in the Ottoman siege of 1565 when it managed to hold out heavy bombardment for over
5184-473: The ability to fire point-blank. The lower the angle of elevation, the higher the stopping power. The first key instance of a trace Italianate was at the Papal port of Civitavecchia , where the original walls were lowered and thickened because the stone tended to shatter under bombardment. The first major battle which truly showed the effectiveness of trace Italienne was the defence of Pisa in 1500 against
5292-483: The appearance of the trace Italienne in early modern Europe, and the difficulty of taking such fortifications, is what resulted in a profound change in military strategy, most importantly, Parker argued, an increase in army sizes necessary to attack these forts. "Wars became a series of protracted sieges", Parker suggests, and open-pitch battles became "irrelevant" in regions where the trace Italienne existed. Ultimately, Parker argues, "military geography", in other words,

In scholarship the castle, as defined above, is generally accepted as a coherent concept, originating in Europe and later spreading to parts of the Middle East, where they were introduced by European Crusaders. This coherent group shared
5508-533: The attacker should they be overcome, but also to allow the large volumes of smoke that the defending cannon would generate to dissipate. Fortifications of this type continued to be effective while the attackers were armed only with cannon, where the majority of the damage inflicted was caused by momentum from the impact of solid shot . Because only low explosives such as black powder were available, explosive shells were largely ineffective against such fortifications. The development of mortars , high explosives , and

#17327725594785616-426: The bailey was the home of the rest of the lord's household and gave them protection. The barracks for the garrison, stables, workshops, and storage facilities were often found in the bailey. Water was supplied by a well or cistern . Over time the focus of high status accommodation shifted from the keep to the bailey; this resulted in the creation of another bailey that separated the high status buildings – such as
5724-502: The best surviving example of the Dutch school of fortifications. When the newly-effective manoeuvrable siege cannon came into military strategy in the fifteenth century, the response from military engineers was to arrange for the walls to be embedded into ditches fronted by earthen slopes (glacis) so that they could not be attacked by destructive direct fire and to have the walls topped by earthen banks that absorbed and largely dissipated
5832-578: The complexity and style of castles, antiquarians found their answer in the Crusades. It seemed that the Crusaders had learned much about fortification from their conflicts with the Saracens and exposure to Byzantine architecture . There were legends such as that of Lalys – an architect from Palestine who reputedly went to Wales after the Crusades and greatly enhanced the castles in the south of
5940-538: The consequent large increase in the destructive power of explosive shells and thus plunging fire rendered the intricate geometry of such fortifications irrelevant. Warfare was to become more mobile. It took, however, many years to abandon the old fortress thinking. Bastion forts were very expensive. Amsterdam 's 22 bastions cost 11 million florins , and Siena in 1544 bankrupted itself to pay for its defences. For this reason, bastion forts were often improvised from earlier defences. Medieval curtain walls were torn down, and
6048-454: The construction of castle sites through the examination of ceramics. The increase in Italy began in the 950s, with numbers of castles increasing by a factor of three to five every 50 years, whereas in other parts of Europe such as France and Spain the growth was slower. In 950, Provence was home to 12 castles; by 1000, this figure had risen to 30, and by 1030 it was over 100. Although

Legends were discredited, and in the case of James of Saint George it was proven that he came from Saint-Georges-d'Espéranche , in France. If the innovations in fortification had derived from the East, it would have been expected for their influence to be seen from 1100 onwards, immediately after
6264-425: The covered way, or covert way. Defenders could move relatively safely in the cover of the ditch and could engage in active countermeasures to keep control of the glacis, the open slope that lay outside the ditch, by creating defensive earthworks to deny the enemy access to the glacis and thus to firing points that could bear directly onto the walls and by digging counter mines to intercept and disrupt attempts to mine
6372-463: The criterion of feudal ownership, thus tying castles to the medieval period; however, this does not necessarily reflect the terminology used in the medieval period. During the First Crusade (1096–1099), the Frankish armies encountered walled settlements and forts that they indiscriminately referred to as castles, but which would not be considered as such under the modern definition. Castles served

Finding that their cannon fire made little impression on these low ramparts, the French and allied besiegers made several bloody and fruitless assaults and then withdrew. The new type of fortification also played
6588-404: The defences could not be directed around curved walls. To prevent this, what had previously been round or square turrets were extended into diamond-shaped points to eliminate potential cover for attacking troops. The ditches and walls channelled the attackers into carefully constructed zwinger , bailey , or similar " kill zone " areas where the attackers had no place to shelter from the fire of

#17327725594786696-427: The defender if it was too small. A smaller horizontal opening could be added to give an archer a better view for aiming. Sometimes a sally port was included; this could allow the garrison to leave the castle and engage besieging forces. It was usual for the latrines to empty down the external walls of a castle and into the surrounding ditch. A postern is a secondary door or gate in a concealed location, usually in
6804-466: The defenders. A further and more subtle change was to move from a passive model of defence to an active one. The lower walls were more vulnerable to being stormed, and the protection that the earthen banking provided against direct fire failed if the attackers could occupy the slope on the outside of the ditch and mount an attacking cannon there. Therefore, the shape was designed to make maximum use of enfilade (or flanking) fire against any attackers on
6912-552: The dominant form of castle in England, Wales, and Ireland well into the 12th century. At the same time, castle architecture in mainland Europe became more sophisticated. The donjon was at the centre of this change in castle architecture in the 12th century. Central towers proliferated, and typically had a square plan, with walls 3 to 4 m (9.8 to 13.1 ft) thick. Their decoration emulated Romanesque architecture , and sometimes incorporated double windows similar to those found in church bell towers. Donjons, which were
7020-643: The early 13th century, Crusader castles were mostly built by Military Orders including the Knights Hospitaller , Knights Templar , and Teutonic Knights . The orders were responsible for the foundation of sites such as Krak des Chevaliers , Margat , and Belvoir . Design varied not just between orders, but between individual castles, though it was common for those founded in this period to have concentric defences. Star fort A bastion fort or trace italienne (a phrase derived from non-standard French, literally meaning 'Italian outline')
7128-413: The economy and justice. However, while castles proliferated in the 9th and 10th centuries the link between periods of insecurity and building fortifications is not always straightforward. Some high concentrations of castles occur in secure places, while some border regions had relatively few castles. It is likely that the castle evolved from the practice of fortifying a lordly home. The greatest threat to
7236-557: The enemies. The enemies' hope was to either ram the gate or climb over the wall with ladders and overcome the defenders. For the invading force these fortifications proved quite difficult to overcome and, accordingly, fortresses occupied a key position in warfare. Passive ring-shaped ( Enceinte ) fortifications of the Medieval era proved vulnerable to damage or destruction when attackers directed cannon fire on to perpendicular masonry wall. In addition, attackers that could get close to
7344-600: The energy of plunging fire . Where conditions allowed, as in Fort Manoel in Malta , the ditches were cut into the native rock, and the wall at the inside of the ditch was simply unquarried native rock. As the walls became lower, they also became more vulnerable to assault. The rounded shape that had previously been dominant for the design of turrets created "dead space", or "dead zones", which were relatively sheltered from defending fire, because direct fire from other parts of
7452-475: The existence or absence of the trace Italienne in a given area, shaped military strategy in the early modern period . This is a profound alteration of the Military Revolution thesis. Parker's emphasis on the fortification as the key element has attracted substantial criticism from some academics, such as John A. Lynn and M. S. Kingra, particularly with respect to the claimed causal link between
7560-498: The fact that lower walls were easier to climb, the ditch was widened so that attacking infantry were still exposed to fire from a higher elevation, including enfilading fire from the bastions. The outer side of the ditch was usually provided with a glacis to deflect cannonballs aimed at the lower part of the main wall. Further structures, such as ravelins , tenailles , hornworks or crownworks , and even detached forts could be added to create complex outer works to further protect
7668-592: The following three centuries. Italian engineers were heavily in demand throughout Europe to help build the new fortifications. The late-seventeenth-century architects Menno van Coehoorn and especially Vauban , Louis XIV 's military engineer, are considered to have taken the form to its logical extreme. "Fortresses... acquired ravelins and redoubts , bonnettes and lunettes , tenailles and tenaillons, counterguards and crownworks and hornworks and curvettes and faussebrayes and scarps and cordons and banquettes and counterscarps ..." The star-shaped fortification had
7776-437: The fort walls. Compared to medieval fortifications , forts became both lower and larger in area, providing defence in depth , with tiers of defences that an attacker needed to overcome in order to bring cannon to bear on the inner layers of defences. Firing emplacements for defending cannon were heavily defended from bombardment by external fire, but open towards the inside of the fort, not only to diminish their usefulness to
7884-592: The garrison to control the surrounding area, and formed a centre of administration, providing the lord with a place to hold court . Building a castle sometimes required the permission of the king or other high authority. In 864 the King of West Francia, Charles the Bald , prohibited the construction of castella without his permission and ordered them all to be destroyed. This is perhaps the earliest reference to castles, though military historian R. Allen Brown points out that
7992-703: The immediate proximity of these fortifications. After the First Crusade, Crusaders who did not return to their homes in Europe helped found the Crusader states of the Principality of Antioch , the County of Edessa , the Kingdom of Jerusalem , and the County of Tripoli . The castles they founded to secure their acquisitions were designed mostly by Syrian master-masons. Their design was very similar to that of
8100-428: The increase was slower in Spain, the 1020s saw a particular growth in the number of castles in the region, particularly in contested border areas between Christian and Muslim lands. Despite the common period in which castles rose to prominence in Europe, their form and design varied from region to region. In the early 11th century, the motte and keep – an artificial mound with a palisade and tower on top –
8208-430: The introduction of portable firearms . Roberts linked military technology with larger historical consequences, arguing that innovations in tactics, drill and doctrine by the Dutch and Swedes (1560–1660), which maximized the utility of firearms, led to a need for more trained troops and thus for permanent forces ( standing armies ). According to Geoffrey Parker in his article, The Military Revolution 1560–1660: A Myth? ,
8316-571: The land he had taken. Between 1066 and 1087, he established 36 castles such as Warwick Castle , which he used to guard against rebellion in the English Midlands . Towards the end of the Middle Ages, castles tended to lose their military significance due to the advent of powerful cannons and permanent artillery fortifications; as a result, castles became more important as residences and statements of power. A castle could act as
8424-414: The lay of the land (the result was often irregular or curvilinear structures). The design of castles was not uniform, but these were features that could be found in a typical castle in the mid-12th century. By the end of the 12th century or the early 13th century, a newly constructed castle could be expected to be polygonal in shape, with towers at the corners to provide enfilading fire for
8532-499: The lord's chambers and the chapel – from the everyday structures such as the workshops and barracks. From the late 12th century there was a trend for knights to move out of the small houses they had previously occupied within the bailey to live in fortified houses in the countryside. Although often associated with the motte-and-bailey type of castle, baileys could also be found as independent defensive structures. These simple fortifications were called ringworks . The enceinte
8640-420: The loss of the donjon. Where keeps did exist, they were no longer square but polygonal or cylindrical. Gateways were more strongly defended, with the entrance to the castle usually between two half-round towers which were connected by a passage above the gateway – although there was great variety in the styles of gateway and entrances – and one or more portcullis. A peculiar feature of Muslim castles in
8748-467: The main living quarters of the castle and usually the most strongly defended point of a castle before the introduction of concentric defence . "Keep" was not a term used in the medieval period – the term was applied from the 16th century onwards – instead " donjon " was used to refer to great towers, or turris in Latin. In motte-and-bailey castles, the keep was on top of the motte. "Dungeon"
8856-461: The main wall from artillery , and sometimes provide additional defensive positions. They were built of many materials, usually earth and brick , as brick does not shatter on impact from a cannonball as stone does. Bastion fortifications were further developed in the late fifteenth and early sixteenth centuries, primarily in response to the French invasion of the Italian peninsula . The French army
8964-444: The move, to elaborate permanent stone constructions, notably the milecastles of Hadrian's Wall . Roman forts were generally rectangular with rounded corners – a "playing-card shape". In the medieval period, castles were influenced by earlier forms of elite architecture, contributing to regional variations. Importantly, while castles had military aspects, they contained a recognisable household structure within their walls, reflecting
9072-438: The multi-functional use of these buildings. The subject of the emergence of castles in Europe is a complex matter which has led to considerable debate. Discussions have typically attributed the rise of the castle to a reaction to attacks by Magyars , Muslims , and Vikings and a need for private defence. The breakdown of the Carolingian Empire led to the privatisation of government, and local lords assumed responsibility for
9180-540: The new fortress design and increases in army sizes during this period. In the nineteenth century, with the development of more powerful artillery and explosive shells, star forts were replaced by simpler but more robust polygonal forts . In the twentieth century, with the development of tanks and aerial warfare during and after the First World War, fixed fortifications became and have remained less important than in previous centuries. Star forts reappeared during
9288-573: The number of castles being built went into decline. This has been partly attributed to the higher cost of stone-built fortifications, and the obsolescence of timber and earthwork sites, which meant it was preferable to build in more durable stone. Although superseded by their stone successors, timber and earthwork castles were by no means useless. This is evidenced by the continual maintenance of timber castles over long periods, sometimes several centuries; Owain Glyndŵr 's 11th-century timber castle at Sycharth
9396-603: The outer edge of the ditch and also any who should reach the base of any of the walls. The indentations in the base of each point on the star sheltered cannons. Those cannons would have a clear line of fire directly down the edge of the neighbouring points, while their point of the star was protected by fire from the base of those points. The evolution of these ideas can be seen in transitional fortifications such as Sarzana in northwest Italy. Thus forts evolved complex shapes that allowed defensive batteries of cannon to command interlocking fields of fire . Forward batteries commanded
9504-424: The residence of the lord of the castle, evolved to become more spacious. The design emphasis of donjons changed to reflect a shift from functional to decorative requirements, imposing a symbol of lordly power upon the landscape. This sometimes led to compromising defence for the sake of display. Until the 12th century, stone-built and earth and timber castles were contemporary, but by the late 12th century
9612-405: The slopes which defended walls deeper in the complex from direct fire. The defending cannon were not simply intended to deal with attempts to storm the walls, but to actively challenge attacking cannon and deny them approach close enough to the fort to engage in direct fire against the vulnerable walls. The key to the fort's defence moved to the outer edge of the ditch surrounding the fort, known as
9720-542: The structures also served as centres of administration and symbols of power. Urban castles were used to control the local populace and important travel routes, and rural castles were often situated near features that were integral to life in the community, such as mills, fertile land, or a water source. Many northern European castles were originally built from earth and timber but had their defences replaced later by stone . Early castles often exploited natural defences, lacking features such as towers and arrowslits and relying on
9828-414: The structures. It was also often necessary to widen and deepen the ditch outside the walls to create a more effective barrier to frontal assault and mining. Engineers from the 1520s were also building massive, gently sloping banks of earth called glacis in front of ditches so that the walls were almost totally hidden from horizontal artillery fire. The main benefit of the glaces was to deny enemy artillery
9936-410: The term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls , arrowslits , and portcullises , were commonplace. European-style castles originated in
10044-571: The wall around the city of Ávila imitated Roman architecture when it was built in 1091. Historian Smail in Crusading warfare argued that the case for the influence of Eastern fortification on the West has been overstated, and that Crusaders of the 12th century in fact learned very little about scientific design from Byzantine and Saracen defences. A well-sited castle that made use of natural defences and had strong ditches and walls had no need for
10152-420: The wall were able to conduct undermining operations in relative safety, as the defenders could not shoot at them from nearby walls, until the development of machicolation . In contrast, the bastion fortress was a very flat structure composed of many triangular bastions , specifically designed to cover each other, and a ditch. To counteract the cannonballs, defensive walls were made lower and thicker. To counteract
10260-413: The walls. The towers would have protruded from the walls and featured arrowslits on each level to allow archers to target anyone nearing or at the curtain wall. These later castles did not always have a keep, but this may have been because the more complex design of the castle as a whole drove up costs and the keep was sacrificed to save money. The larger towers provided space for habitation to make up for
10368-413: The walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain wall from positions protected from direct fire. Many bastion forts also feature cavaliers , which are raised secondary structures based entirely inside the primary structure. Their predecessors, medieval fortresses , were usually placed on high hills . From there, arrows were shot at
10476-460: The word castella may have applied to any fortification at the time. In some countries the monarch had little control over lords, or required the construction of new castles to aid in securing the land so was unconcerned about granting permission – as was the case in England in the aftermath of the Norman Conquest and the Holy Land during the Crusades . Switzerland is an extreme case of there being no state control over who built castles, and as
10584-625: Was called a hall-house. Historian Charles Coulson states that the accumulation of wealth and resources, such as food, led to the need for defensive structures. The earliest fortifications originated in the Fertile Crescent , the Indus Valley , Europe, Egypt, and China where settlements were protected by large walls. In Northern Europe , hill forts were first developed in the Bronze Age , which then proliferated across Europe in
10692-477: Was common, and usually between local lords. Castles were introduced into England shortly before the Norman Conquest in 1066. Before the 12th century castles were as uncommon in Denmark as they had been in England before the Norman Conquest. The introduction of castles to Denmark was a reaction to attacks from Wendish pirates, and they were usually intended as coastal defences. The motte and bailey remained
10800-406: Was equipped with new cannon and bombards that were easily able to destroy traditional fortifications built in the Middle Ages . Star forts were employed by Michelangelo in the defensive earthworks of Florence , and refined in the sixteenth century by Baldassare Peruzzi and Vincenzo Scamozzi . The design spread out of Italy in the 1530s and 1540s. It was employed heavily throughout Europe for
10908-430: Was in short supply. Although stone construction would later become common elsewhere, from the 11th century onwards it was the primary building material for Christian castles in Spain, while at the same time timber was still the dominant building material in north-west Europe. Historians have interpreted the widespread presence of castles across Europe in the 11th and 12th centuries as evidence that warfare
11016-556: Was introduced to Europe in the 14th century, it did not significantly affect castle building until the 15th century, when artillery became powerful enough to break through stone walls. While castles continued to be built well into the 16th century, new techniques to deal with improved cannon fire made them uncomfortable and undesirable places to live. As a result, true castles went into decline and were replaced by artillery star forts with no role in civil administration, and château or country houses that were indefensible. From
11124-420: Was made in the upper storey of the gatehouse for accommodation so the gate was never left undefended, although this arrangement later evolved to become more comfortable at the expense of defence. During the 13th and 14th centuries the barbican was developed. This consisted of a rampart , ditch, and possibly a tower, in front of the gatehouse which could be used to further protect the entrance. The purpose of
11232-419: Was not always the case and there are instances where a motte existed on its own. "Motte" refers to the mound alone, but it was often surmounted by a fortified structure, such as a keep, and the flat top would be surrounded by a palisade . It was common for the motte to be reached over a flying bridge (a bridge over the ditch from the counterscarp of the ditch to the edge of the top of the mound), as shown in
11340-417: Was often the weakest part in a circuit of defences. To overcome this, the gatehouse was developed, allowing those inside the castle to control the flow of traffic. In earth and timber castles, the gateway was usually the first feature to be rebuilt in stone. The front of the gateway was a blind spot and to overcome this, projecting towers were added on each side of the gate in a style similar to that developed by
11448-422: Was still in use by the start of the 15th century, its structure having been maintained for four centuries. At the same time there was a change in castle architecture. Until the late 12th century castles generally had few towers; a gateway with few defensive features such as arrowslits or a portcullis; a great keep or donjon, usually square and without arrowslits; and the shape would have been dictated by
11556-425: Was the castle's main defensive enclosure, and the terms "bailey" and "enceinte" are linked. A castle could have several baileys but only one enceinte. Castles with no keep, which relied on their outer defences for protection, are sometimes called enceinte castles; these were the earliest form of castles, before the keep was introduced in the 10th century. A keep was a great tower or other building that served as
11664-516: Was the most common form of castle in Europe, everywhere except Scandinavia. While Britain, France, and Italy shared a tradition of timber construction that was continued in castle architecture, Spain more commonly used stone or mud-brick as the main building material. The Muslim invasion of the Iberian Peninsula in the 8th century introduced a style of building developed in North Africa reliant on tapial , pebbles in cement, where timber
