In geology , a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion , either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.
128-533: Funchal ( Portuguese pronunciation: [fũˈʃal] ) is the capital, largest city and the municipal seat of Portugal 's Autonomous Region of Madeira , bordered by the Atlantic Ocean . The city has a population of 105,795, making it the sixth largest city in Portugal. Because of its high cultural and historical value, Funchal is one of Portugal's main tourist attractions; it is also popular as
256-438: A central volcano or intrusion. Though they appear to originate in the central intrusion, the dikes often have a different age and composition from the intrusion. These radial swarms may have formed over the intrusion and were later cut by the rising body of magma, or the crust was already experiencing regional tension and the intrusion triggered formation of the fissures. In rock of the oceanic crust, pillow lava erupted onto
384-929: A county of the Christian Kingdom of León in 868, and ultimately as an independent Kingdom with the Treaty of Zamora in 1143. During the Age of Discovery , the Kingdom of Portugal established itself as a major economic and political power, largely through its maritime empire, which extended mostly along the South Atlantic and Indian Ocean coasts. Portuguese explorers and merchants were instrumental in establishing trading posts and colonies that enabled control over spices and slave trades. While Portugal expanded its influence globally, its political and military power faced internal and external challenges towards
512-460: A curtain of fire where lava erupts along the entire length of a fissure several kilometers long. However, the length of erupting fissure diminishes over time, becoming focused on a short segment of less than half a kilometer. The minimum possible width of a dike is determined by the balance between magma movement and cooling. There may be more than one injection of magma along a given fissure. When multiple injections are all of similar composition,
640-688: A nobility , which played a key social and political role during the Middle Ages . It was under the Visigoths that the Church began to play an important part within the state. As the Visigoths did not learn Latin from the local people, they had to rely on bishops to continue the Roman system of governance. The laws were made by councils of bishops, and the clergy emerged as a high-ranking class. Today's continental Portugal, along with most of modern Spain,
768-497: A sill is a sheet intrusion that forms within and parallel to the bedding. Mafic magma (fluid magma low in silica) usually reaches the surface through fissures, forming dikes. At the shallowest depths, dikes form when magma rises into an existing fissure. In the young, shallow dikes of the Hawaiian Islands, there is no indication of forceful intrusion of magma. For example, there is little penetration of magma into

They are studied by geologists for the clues they provide on volcanic plumbing systems . They also record ancient episodes of extension of the Earth's crust , since large numbers of dikes ( dike swarms ) are formed when the crust is pulled apart by tectonic forces. The dikes show the direction of extension, since they form at right angles to
2688-543: A ring fracture. Magma rising into the ring fracture produces a ring dike. Good examples of ring dikes and cone sheets are found in the Ardnamurchan peninsula of Scotland. A feeder dike is a dike that acted as a conduit for magma moving from a magma chamber to a localized intrusion . For example, the Muskox intrusion in arctic Canada was fed by a large dike, with a thickness of 150 meters. A sole injection

#17327722644292816-411: A shallow magma chamber. Cone sheets form when magma is injected into a shallow magma chamber, which lifts and fractures the rock beds above it. The fractures take the form of a set of concentric cones dipping at a relatively shallow angle into the magma chamber. When the caldera is subsequently emptied by explosive volcanic activity, the roof of the magma chamber collapses as a plug of rock surrounded by
2944-580: A single railway. The government of Portugal quietly accepted the ultimatum and withdrew their forces from the disputed area, leading to a widespread backlash among the Portuguese public, who viewed acceptance of the British demands as a humiliation. On 5 October 1910, a coup d'état overthrew the near 800 year-old Monarchy and the Republic was proclaimed. During World War I, Portugal helped the Allies fight

3456-457: Is concentrated on the tip of the propagating fracture. In effect, the magma wedges apart the brittle rock in a process called hydraulic fracture . At greater depths, where the rock is hotter and less brittle, the magma forces the rock aside along brittle shear planes oriented 35 degrees to the sides of the dock. This bulldozer-like action produces a blunter dike tip. At the greatest depths, the shear planes become ductile faults, angled 45 degree from
3584-582: Is located east of the city, in the municipality of Santa Cruz . The airport was one of the most dangerous airports in the world due to the limited flat space in close proximity to cliffs, but the extension of the runway on concrete pillars in the sea has improved safety. The Port of Funchal was the only major port in Madeira. Since 2007 it has been fully dedicated to passenger transport (cruise ships and ferries) and other tourist-related boats and yachts. In that year all remaining fishing activity and cargo trade
3712-408: Is rapid flow of molten magma through a fissure, the magma tends to erode the walls, either by melting the wall rock or by tearing off fragments of wall rock. This widens the fissure and increases flow. Where flow is less rapid, the magma may solidify next to the wall, narrowing the fissure and decreasing flow. This causes flow to become concentrated at a few points. At Hawaii, eruptions often begin with
3840-473: Is seen in the Higganum dike set of New England. This dike set consists of individual dikes that are typically four kilometers in length at the surface and up to 60 meters wide. These short segments form longer groups extending for around 10 km. The entire set of dikes forms a line extending for 250 km. Individual segments overlap, with the overlapping portions thinner, so that the combined thickness of

4096-695: Is the P-wave velocity of the host rock (essentially, the speed of sound in the rock). This formula predicts that dikes will be longer and narrower at greater depths below the surface. The ratio of thickness to length is around 0.01 to 0.001 near the surface, but at depth it ranges from 0.001 to 0.0001. A surface dike 10 meters in thickness will extend about 3 km, while a dike of similar thickness at depth will extend about 30 km. This tendency of intruding magma to form shorter fissures at shallower depths has been put forward as an explanation of en echelon dikes. However, en echelon dikes have also been explained as

The growth of viticulture in Madeira expanded when the sugar industry was attacked by cheaper exports from the New World and Africa, but also from various epidemics and the after-effects of the 1566 privateer sacks. In the 17th century, commercial treaties with England brought increased investments to a business that was still insular. Many commercial wine-makers from England moved to
9600-438: The dike is described as a multiple dike . However, subsequent injections are sometimes quite different in composition, and then the dike is described as a composite dike . The range of compositions in a composite dike can go all the way from diabase to granite , as is observed in some dikes of Scotland and northern Ireland. After the initial formation of a dike, subsequent injections of magma are most likely to take place along
9728-426: The direction of maximum extension. The thickness of a dike is much smaller than its other two dimensions, and the opposite walls are roughly parallel, so that a dike is more or less constant in thickness. The thickness of different dikes can range from a few millimeters to hundreds of meters, but is most typically from about a meter to a few tens of meters. The lateral extent can be tens of kilometers, and dikes with
9856-460: The earthquake, Joseph I gave his prime minister more power, and Carvalho de Melo became an enlightened despot . In 1758 Joseph I was wounded in an attempted assassination. The Marquis of Távora , several members of his family and even servants were tortured and executed in public with extreme brutality (even by the standards of the time), as alleged part of the Távora affair . The following year,
9984-435: The empire. Dike (geology) A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve
10112-408: The empire. Roman occupation suffered a setback in 155 BC, when a rebellion began in the north. The Lusitanians and other native tribes, under the leadership of Viriathus , wrested control of all of western Iberia. Rome sent legions to quell the rebellion but were unsuccessful. Roman leaders bribed Viriathus's allies to kill him in 139 BC; he was replaced by Tautalus . In 27 BC, Lusitania gained
10240-489: The end of the 16th century. The dynastic crisis marked the beginning of the country's political decline that led to the Iberian Union (1580-1640), a period in which Portugal was united under Spanish rule. While maintaining a degree of self-governance, the union strained Portugal’s autonomy and drew it into conflicts with European powers which targeted Portuguese territories and trade routes. Portugal's prior opulence
10368-660: The entirety of the Autonomous Region of Madeira, and is a suffragan see under the Archdiocese of Lisbon . Its focus is the Sé Cathedral , located in civil parish of Sé , dedicated to Nossa Senhora da Assunção ( English: Our Lady of the Assumption ) while its patron saint is Saint James . Anglican services have been held at Holy Trinity Church in Funchal (Rua do Quebra Costas) since 1822, although
10496-603: The first cities he founded is Vimaranes, known today as Guimarães – "birthplace of the Portuguese nation" or the "cradle city". After annexing the County of Portugal into one of the counties that made up the Kingdom of Asturias , King Alfonso III of Asturias knighted Vímara Peres, in 868, as the First Count of Portus Cale (Portugal). The region became known as Portucale , Portugale , and simultaneously Portugália . With
10624-515: The first recorded Protestant service took place in 1774. The Holy Trinity Church also takes care of the British Cemetery of Funchal . Funchal Baptist Church was established in Madeira in 1976. It is located at Rua Silvestre Quintino de Freitas, and provides English services in the morning and Portuguese in the evening. The Church of Jesus Christ of Latter-day Saints was established on Madeira in 1983. A few congregations have developed and
10752-403: The forced abdication of Alfonso III in 910, the Kingdom of Asturias split into three separate kingdoms; they were reunited in 924 under the crown of León . In 1093 Alfonso VI of León bestowed the county to Henry of Burgundy and married him to his daughter, Teresa of León . Henry thus became Henry, Count of Portugal and based his newly formed county from Bracara Augusta (modern Braga ). At
10880-552: The formal creation of the Port of Funchal, and later the establishment of the Santa Catarina Airport, Funchal turned into a major international tourist destination supported by a series of hotels and ocean-front residences. Funchal is located inside a natural amphitheatre -shaped valley, with gentle slopes beginning at the coast which rise to 1200 metres and provide a natural shelter for early settlers In addition to
11008-499: The governor, Francisco de Sales Gonçalves Zarco da Câmara, did not take any hostile action. Meanwhile, the armada anchored off the beach of Formosa, disembarked a contingent of 800 men that marched towards the city in three columns, encountering no resistance until the main bridge in São Paulo. At the bridge the privateers encountered a force from the small fort, with a few small-caliber pieces, which were quickly routed in confusion. At
11136-503: The influx of gold into the royal treasury, supplied largely by the royal fifth (tax on precious metals) from the Portuguese colonies of Brazil and Maranhão . Most estimates place the number of Portuguese migrants to Colonial Brazil during the gold rush of the 18th century at 600,000. This represented one of the largest movements of European populations to their colonies, during colonial times. In 1738 Sebastião José de Carvalho e Melo , later ennobled as 1st Marquis of Pombal , began
11264-702: The island of Crete , which were being exported in greater numbers. By the end of the 16th century, the celebrated English poet and playwright , William Shakespeare , cited the important export and notoriety of the Madeiran Malvasia castes: in Richard III the Duke of Clarence, the brother of King Edward IV selected a death by drowning in a barrel of Madeira. Later, in Shakespeare's Henry IV he has Poins censure Falstaff for having sold his soul to
11392-437: The island, changing the economy, architecture forms and lifestyle of the community. This incremental growth expanded the city with new estates, and a new merchant class that populated the urban quarters. Generally, there were many new three-floor homes with an intermediary service floor, a floor for storage and wine-cellars, and in some cases a tower to watch the port and monitor shipping in the harbour. Various island governors and
11520-694: The joining of the two crowns deprived Portugal of an independent foreign policy, and led to its involvement in the Eighty Years' War between Spain and the Netherlands. War led to a deterioration of relations with Portugal's oldest ally, England , and the loss of Hormuz , a strategic trading post located between Iran and Oman . From 1595 to 1663 the Dutch-Portuguese War primarily involved Dutch companies invading Portuguese colonies and commercial interests in Brazil, Africa, India and
11648-572: The liberation during the Peninsular War , Portugal endured a period marked by a civil war between liberals and absolutists from 1828 to 1834. The monarchy was overthrown in the 1910 revolution, which led to the establishment of the Portuguese First Republic . A phase of unrest ultimately led to the rise of authoritarian regimes of the Ditadura Nacional and the Estado Novo . Democracy was finally restored following
11776-698: The local inhabitants. St. Martin of Braga was a particularly influential evangelist. In 429, the Visigoths moved south to expel the Alans and Vandals and founded a kingdom with its capital in Toledo . From 470, conflict between the Suebi and Visigoths increased. In 585, the Visigothic King Liuvigild conquered Braga and annexed Gallaecia; the Iberian Peninsula was unified under a Visigothic Kingdom . A new class emerged, unknown in Roman times:
11904-415: The long axis of the volcanic shield. Sills and stocks are occasionally present in the complexes. They are abruptly truncated at the margins of summit calderas. Typically, there are about 50 to 100 dikes per kilometer at the center of the rift zone, though the density can be as high as 500 per kilometer and the dikes then make up half the volume of the rock. The density drops to 5 to 50 per kilometer away from
12032-688: The magma fractured and disintegrated the rock at its advancing tip rather than prying the rock apart. Other dikes may have formed by metasomatism , in which fluids moving along a narrow fissure changed the chemical composition of the rock closest to the fissure. There is an approximate relationship between the width of a dike and its maximum extent, expressed by the formula: 2 w 2 b = 2.25 P e x ρ h o s t V P 2 {\displaystyle {\frac {2w}{2b}}={\frac {2.25P_{ex}}{\rho _{host}V_{P}^{2}}}} Here w {\displaystyle w}
12160-401: The margins. Here the dike rock fractures into columns as it cools and contracts. These are usually 5- to 6-sided, but 3- to 4-sided columns are also common. These are fairly uniform in size within a single dike, but range from a few centimeters to over 0.3 meters across in different dikes, tending to be thicker in wider dikes. Larger columns are likely a consequence of slower cooling. Dike rock
12288-402: The military architect Mateus Fernandes III was sent to Funchal in order to completely modify the defensive system of the city. Evidence of the work produced by this architect was published in the "Mapa de Mateus Fernandes" (1573), considered to be the oldest plan of the island of Funchal. The document identifies the major defenses of the city, which included a large fortification in the area around
12416-489: The most productive on the island, quickly permitted Funchal to develop an urban core and surpass the populations of other settlements. In the early 15th century, Álvaro Fernandes became the commander of Funchal. As part of its administrative role, the settlement received its primary lighthouse between 1452 and 1454, when it was elevated to the status of vila and municipal seat. Funchal became an important transfer point for European commercial interests. Christopher Columbus
12544-658: The port of the Gauls. Around 200 BC, the Romans took Iberia from the Carthaginians during the Second Punic War . In the process they conquered Cale, renaming it Portus Cale ('Port of Cale') and incorporating it into the province of Gallaecia . During the Middle Ages , the region around Portus Cale became known by the Suebi and Visigoths as Portucale . The name Portucale changed into Portugale during
12672-552: The reign of King José I, he banned the import of black slaves into mainland Portugal and India, not for humanitarian reasons, but because they were a necessary work force in Brazil. At the same time, he encouraged the trade of black slaves ("the pieces", in the terms of that time) to that colony, and with the support and direct involvement of the Marquis of Pombal, two companies were founded - the Companhia do Grão-Pará e Maranhão and
12800-402: The road near Carreira, the attackers were confronted by a small group of Franciscan friars, who were quickly dispatched. Funchal's fortifications were finally assaulted by land, where its defense was thin; the defenders could not even reposition many of the cannons directed towards the sea. The city suffered a violent sack that lasted fifteen days, after which little remained. The following year,
12928-431: The rock, always opening a path along a plane normal to the minimum principal stress . This is the direction in which the crust is under the weakest compression and so requires the least work to fracture. At shallow depths, where the rock is brittle, the pressurized magma progressively fractures the rock as it advances upwards. Even if the magma is only slightly pressurized compared with the surrounding rock, tremendous stress
13056-494: The same period. The region came under Roman control in the second century BCE, followed by a succession of Germanic peoples and the Alans from the fifth to eighth centuries CE. Muslims conquered most of the Iberian Peninsula in the eighth century CE, but were gradually expelled by the Christian Reconquista over the next several centuries. Modern Portugal began taking shape during this period, initially as
13184-429: The sea floor is underlain by sheeted dike complexes that preserve the conduits through which magma reached the ocean floor at mid-ocean ridges . These sheeted dikes characteristically show a chilled margin on only one side, indicating that each dike was split in half by a subsequent eruption of magma. Ring dikes and cone sheets are special types of dikes associated with caldera volcanism. These are distributed around
13312-569: The sides of the dike. At depths where the rock is completely plastic, a diapir (a rising plug of magma) forms instead of a dike. The walls of dikes often fit closely back together, providing strong evidence that the dike formed by dilatation of a fissure. However, a few large dikes, such as the 120-meter-thick Medford dike in Maine, US, or the 500-meter-thick Gardar dike in Greenland, show no dilatation. These may have formed by stoping , in which
13440-430: The south. Early in the first millennium BC, several waves of Celts invaded Portugal from Central Europe and intermarried with the local populations to form several different ethnic groups. The Celtic presence is patent in archaeological and linguistic evidence. They dominated most of northern and central Portugal, while the south maintained its older character (believed non-Indo-European, likely related to Basque ) until
13568-675: The southern coast of Madeira . Funchal is a cosmopolitan and panoramic city, with parks, shops and hotels. The municipality ( Portuguese : concelho ) and city ( Portuguese : cidade ) are one administrative division, administered by an executive and legislative committee in the city hall. Local communities, are administered at the civil parish levels, through their own legislative bodies and executives. Funchal comprises ten civil parishes ( Portuguese : freguesias ) based on traditional religious districts ( Portuguese : paróquias ): Madeira Airport , often known as Funchal Airport (code: FNC) and officially Cristiano Ronaldo International Airport,
13696-503: The southern coast, from Machico until Fajã da Ovelha, making Funchal the most important industrial centre of the industry. By the end of the century, fronting the Order of Christ , D. Manuel , Duke of Beja , expanded the support of the local community; he ordered the construction of the administrative Paços do Concelho and the Paços dos Tabeliães (completed in 1491), raised the construction of
13824-539: The status of Roman province . Later, a northern province was separated from the province of Tarraconensis , under Emperor Diocletian 's reforms, known as Gallaecia . There are still ruins of castros ( hill forts ) and remains of the Castro culture , like Conímbriga , Mirobriga and Briteiros . In 409, with the decline of the Roman Empire , the Iberian Peninsula was occupied by Germanic tribes . In 411, with
13952-511: The streets of the Old Town, particularly in the Rua de Santa Maria.The doors of houses, abandoned shops, deteriorated areas received a new life, in order to sensitize people, towards the art and culture that fills these spaces. Funchal is twinned with: Portugal – in Europe (green & dark grey) – in the European Union (green) Portugal , officially
14080-430: The surface, forming a rock type called diabase . The grain size varies systematically across the dike, with the coarsest grains normally at the center of the dike. Dikes formed at shallow depth commonly have a glassy or fine-grained chilled margin 1 to 5 cm thick, formed where the magma was rapidly cooled by contact with the cold surrounding rock. Shallow dikes also typically show columnar jointing perpendicular to
14208-669: The territories corresponding to modern Portugal. As elsewhere in Western Europe, there was a sharp decline in urban life during the Dark Ages . Roman institutions disappeared in the wake of the Germanic invasions with the exception of ecclesiastical organizations, which were fostered by the Suebi in the fifth century and adopted by the Visigoths afterwards. Although the Suebi and Visigoths were initially followers of Arianism and Priscillianism , they adopted Catholicism from
14336-520: The throne of Portugal. John of Aviz, later John I of Portugal , defeated the Castilians in the Battle of Aljubarrota , and the House of Aviz became the ruling house. The new ruling dynasty led Portugal to the limelight of European politics and culture. They created and sponsored literature, such as a history of Portugal, by Fernão Lopes . Portugal spearheaded European exploration of the world and
14464-526: The two overlapped portions is about the same as the thickness of a single segment. Other examples of en echelon dikes are the Inyo dike of Long Valley, California , US; the Jagged Rocks complex, Arizona , US; and the dikes of oceanic spreading centers . Dikes range in composition from basaltic to rhyolitic , but most are basaltic. The texture is typically slightly coarser than basalt erupted at
14592-611: The urbanized area, the municipality includes the Ilhas Selvagens (English: Savage Islands ), a nature reserve located 294 km (183 mi) south of the capital. According to the Köppen climate classification , Funchal has a hot-summer Mediterranean climate ( Köppen : Csa ) bordering on a tropical savanna climate (Köppen: As ). It is the warmest city in Portugal, with an annual temperature of 20.1 °C (68.2 °F). The climate can be divided into two main seasons:
14720-575: The vast Umayyad Caliphate's empire of Damascus , until its collapse in 750. That year the west of the empire gained its independence under Abd-ar-Rahman I with the establishment of the Emirate of Córdoba . The Emirate became the Caliphate of Córdoba in 929, until its dissolution in 1031, into 23 small kingdoms, called Taifa kingdoms. The governors of the taifas proclaimed themselves Emir of their provinces and established diplomatic relations with
14848-400: The walls of dikes even when the walls consist of highly porous volcanic clinker, and little wall material breaks off into the molten magma. These fissures likely open as a result of bulging of the rock beds above a magma chamber that is being filled with magma from deeper in the crust. However, open fractures can exist only near the surface. Magma deeper in the crust must force its way through
14976-586: The war of Christian reconquest. At the end of the 9th century, the region of Portugal between the rivers Minho and Douro, was reconquered from the Moors by nobleman and knight Vímara Peres on the orders of King Alfonso III of Asturias . Finding many towns deserted, he decided to repopulate and rebuild them. Vímara Peres elevated the region to the status of County , naming it the County of Portugal after its major port city – Portus Cale or modern Porto . One of
15104-557: The west of Scotland and running into northern England record the early opening of the Atlantic Ocean. Dike swarms are forming in the present day along the divergent plate boundary running through Iceland. Dike swarms often have a great cumulative thickness: Dikes in Iceland average 3 to 5 meters in width, but one 53-kilometer stretch of coast has about 1000 dikes with total thickness of 3 kilometers. The world's largest dike swarm
15232-457: The west, and Santa Cruz, Machico and Caniçal to the east. Today Funchal is a major tourist town, with hotels, port, and an international airport Cristiano Ronaldo International Airport (FNC), located in the nearby municipality of Santa Cruz. Besides the city of Funchal, tourist destinations include: Ribeira Brava , Curral das Freiras , Porto Moniz , Santana , the Laurisilva forest,
15360-490: The wine's quality. This was the first attempt to control wine quality and production in Europe. He imposed strict law upon all classes of Portuguese society, along with a widespread review of the tax system. These reforms gained him enemies in the upper classes. Lisbon was struck by a major earthquake on November 1st 1755 , magnitude estimated to have been between 7.7–9.0, with casualties ranging from 12,000 to 50,000. Following
15488-441: Was banished to his estate at Pombal , where he died in 1782. Historians argue that Pombal's "enlightenment," while far-reaching, was primarily a mechanism for enhancing autocracy at the expense of individual liberty and especially an apparatus for crushing opposition, suppressing criticism, and furthering colonial exploitation and consolidating personal control, and profit. In 1807 Portugal refused Napoleon 's demand to accede to
15616-586: Was elected leader in 718 by many of the ousted Visigoth nobles. Pelagius called for the remnants of the Christian Visigothic armies to rebel against the Moors and regroup in the unconquered northern Asturian highlands, known today as the Cantabrian Mountains , in north-west Spain. After defeating the Moors in the Battle of Covadonga in 722, Pelagius was proclaimed king, thus founding the Christian Kingdom of Asturias and starting
15744-455: Was exiled to Funchal. Polish Field Marshal Józef Piłsudski in order to recuperate his health. Winston Churchill travelled there on holidays and was known to have painted a few paintings during his visits and Fulgencio Batista stopped over en route to his exile in Spain. The presence of these notable visitors marked a period when Funchal became a center of tourism and therapeutic health. With
15872-537: Was further exacerbated by a series of events, such as the Portuguese Restoration War and the 1755 Lisbon earthquake , which destroyed the city and damaged the empire's economy. The Napoleonic Wars motivated the Portuguese royal family to relocate to Brazil in 1807. This event reshaped the relationship between Portugal and Brazil, culminating in Brazilian independence in 1822 . Following
16000-649: Was invaded from the South and became part of al-Andalus between 726 and 1249, following the Umayyad Caliphate conquest of the Iberian Peninsula . This rule lasted decades in the North, up to five centuries in the South. After defeating the Visigoths in a few months, the Umayyad Caliphate started expanding rapidly in the peninsula. Beginning in 726, the land that is now Portugal became part of
16128-451: Was moved to the newly developed port of Caniçal , 12 mi (19 km) to the east. A ferry service between Funchal and Portimão , on the mainland, provided by Naviera Armas sailed weekly from 2008, but was discontinued in 2013 due to a dispute over harbour fees. In summer 2018 it was re-instated, but as a seasonal service from July to September, being operated by Grupo Sousa using Naviera Armas's ship Volcán de Tijarafe , that provided
16256-796: Was one of the early settlers, but later many of the merchant families established commercial interests on the island, including: João d'Esmenaut from the Picardy region , the Lomelino from Genoa , the Mondragão from Biscay , the Acciauoli from Florence , the Bettencourts from France, the Lemilhana Berenguer from Valencia and many others. During the second half of the 15th century, the sugar industry expanded significantly along
16384-504: Was proclaimed King of Portugal by his soldiers. This is traditionally taken as the occasion when the County of Portugal became the independent Kingdom of Portugal and, in 1129, the capital city was transferred from Guimarães to Coimbra. Afonso was recognized as the first king of Portugal in 1143 by King Alfonso VII of León , and in 1179 by Pope Alexander III as Afonso I of Portugal. Afonso Henriques and his successors, aided by military monastic orders , continued pushing southwards against
