An urstromtal (plural: Urstromtäler ) is a type of broad glacial valley , for example, in northern Central Europe , that appeared during the ice ages , or individual glacial periods of an ice age, at the edge of the Scandinavian ice sheet and was formed by meltwaters that flowed more or less parallel to the ice margin. Urstromtäler are an element of the glacial series . The term is German and means "ancient stream valley". Although often translated as "glacial valley", it should not be confused with a valley carved out by a glacier. More accurately some sources call them "meltwater valleys" or "ice-marginal valleys".
49-654: Important for the emergence of the Urstromtäler is the fact that the general lie of the land on the North German Plain and in Poland slopes down from south to north. Thus the ice sheet that advanced from Scandinavia flowed into a rising terrain. The meltwaters could therefore only flow for a short distance southwards over the sandurs (outwash plains) before having to find a way to the North Sea basin that
98-538: A four-winged building with enclosed courtyard and outside dimensions of 50 x 60 metres. In converting it into a Renaissance palace, architecture and ornamentation were influenced by the Weser Renaissance style, of which the Wolfsburg is a typical example, as well as the most northeasterly one. The builders, stonemasons and sculptors who took part had also been involved in building palaces in
147-630: A sandur and a terminal moraine . Urstromtäler of Central Europe (Poland, Germany and Denmark especially) were directly connected to the North Atlantic Ocean, via the Channel River , during Pleistocene maximum glaciations, i.e. at times of confluence of the British and Fennoscandian ice-sheets in the intervening North Sea. Urstromtäler should not be confused with tunnel valleys . The latter are formed beneath, not in front of,
196-480: A section of the building that had fallen into disrepair, demolished and erected in its place the present north wing with the entranceway to the schloss . When he died in 1583, his relative Günzel, his brother Günther and their uncle Jakob continued the work and built the ostentatious east wing. Then followed the south wing as the Palas with its Great Hall. Not until 1620 was the palace completed in its present shape as
245-523: Is a medieval lowland and water castle in North Germany that was first mentioned in the records in 1302, but has since been turned into a Renaissance schloss or palace. It is located in eastern Lower Saxony in the town of Wolfsburg named after it and in whose possession it has been since 1961. The Wolfsburg developed from a tower house on the River Aller into a water castle with
294-771: Is drained by rivers that flow northwards into the North Sea or the Baltic and tributaries to the Rhine river that flows West. The Rhine, Ems , Weser , Elbe and Havel are the most important rivers which drain the North German Lowlands into the North Sea and created woods in their flood plains and folds, e.g. the Spreewald ("Spree Forest"). Only a small area of the North German Plain falls within
343-455: Is integrated as an element of the west wing into the main structure and is recognisable as such by its lack of decoration and windows. The tower has an area of 9 x 9 metres, a height of around 23 metres and wall thickness of up to 3 metres. It is the oldest part of the whole site and its origins may go back to the 13th century. In the internal corners of the courtyard there are three other towers with staircases that enable
392-460: Is made out by the four brothers: Borchard, Günzel, Günter and Werner von Bartensleben. They were a ministerialis family (unfree knights), who came from the village of Bartensleben near Helmstedt . Their family members appeared at that time in the region, including in 1288 at the castle in Vorsfelde. In addition there is another record dating to 1135, but it is not clear whether this refers to
441-742: Is one of the major geographical regions of Germany . It is the German part of the North European Plain . The region is bounded by the coasts of the North Sea and the Baltic Sea to the north, Germany's Central Uplands ( die Mittelgebirge ) to the south, by the Netherlands to the west and Poland to the east. In the west, the southern boundary of the North German Plain is formed by the Lower Saxon Hills : specifically
490-497: The Altes Land near Hamburg , which is characterised by relatively mild temperatures year round due to the proximity of the North Sea and lower Elbe river, providing excellent conditions for fruit production. Azonal vegetation complexes of moors, riparian forests, fens and water bodies originally stretched along the rivers Ems , Weser , Elbe , Havel and Spree . Distinctive salt marshes , tideflats and tidal reed beds in
539-864: The Elbe–Havel Canal or the Oder–Havel Canal . Because the land in North America and on the Russian Plain tilts towards the south, the formation of Urstromtäler there during the ice age did not take place. The Mississippi River and its tributaries carried the meltwaters of the North American ice sheet away. In Eastern Europe the meltwaters flowed down the river basins of the Dnieper , Don and Volga . Urstromtäler , whether sandy or boggy, posed considerable obstacles to movement in

#1732772550741588-637: The Middle Ages . As a result, the trade routes converged on points where the valley could be crossed comparatively easily. These hubs thus became favourite sites for the founding of towns or castles. Examples from the German state of Brandenburg include Berlin , Fürstenwalde , Luckenwalde and Baruth/Mark , and from Lower Saxony the town of Vorsfelde and Wolfsburg Castle .

Since the 17th century the castle has been a four-sided, solid building surrounding an inner courtyard. The main body of the castle thus has four wings, which are named after the points of the compass. The upper outline of the castle with its finely decorated cross-gables, lucarnes and pointed roofs of
686-433: The bergfried , is the oldest surviving part of the present site. It was accessible halfway up by a wooden staircase or ladder that could be hauled up in the face of enemy attack. To begin with, it may have been the tower house of the von Bartenslebens themselves. Over time it did not do justice to as an aristocratic residence and domestic building, and as a consequence other buildings and fortifications were constructed. Within

The natural vegetation of the North German Plain is thought to have been forest formed mainly by the dominant species European Beech (Fagetalia). According to Germany's Federal Agency for Nature Conservation, the BfN , the North German Plain consists of the natural regions listed below. Where possible, their names have been derived from authoritative English-language source(s), as indicated by
784-482: The wall towers form a contrast with the fortification-like walls. Outsize stone figures on horseback decorate the palace entrance with its round arch. Above the portal there are stone shields with the coat of arms of the Bartenslebens, chimera ( Neidköpfe ) and equestrian figures. The portal architecture, like the terrace with its great perron on the park side, is a 19th-century addition. The bergfried

The Baruth, Berlin and Eberswalde Urstromtäler are common short names for the associated sections of the Urstromtal in Brandenburg . In addition to the large main valleys there are also numerous smaller meltwater valleys ( Urstromtalungen ). Their appearance is similar to that of the great Urstromtäler , but they are considerably shorter. They are also not linked to
882-595: The Aller river was artificially confined and controlled. In 1574, thanks to his great fortune, Hans von Bartensleben , the Wealthy ( der Reiche ), was able to begin the conversion of the castle. For this work he employed masons, stonemasons and carpenters, whom he paid. The socage rendered him by the peasants of the villages of the Vorsfelder Werder provided free manual labour as well as horses and carts. When
931-463: The Bartenslebens unduly imposed on them, the farmers complained (for example in 1600) to their overlord, Duke Henry Julius of Brunswick-Wolfenbüttel . From then on, socage was restricted to "only" ten hours in summer and eight hours in winter, twice a week, although travel time from the villages, which were up to 15 kilometres away, was not counted. Hans the Wealthy had the Red House ( Rotes Haus ),

In the loess areas of the lowland are found the oldest settlement locations in Germany ( Linear Pottery culture ). The northeastern part of the plain (Young Drift) is geomorphologically distinct and contains a multitude of lakes (e.g.
1029-544: The Fulda Gap option was seen as the most likely invasion route because of easier and closer access to tactical and strategic goals important for an invasion of Western Europe. Of the two North German plain invasion options, the southern route of the attack, which had the better strategic opportunities, would have been led by the Soviet Third Shock Army .

The retreating glaciers left this landscape behind around 16,000 to 13,000 years ago. In comparison, the dry plains of northwestern Germany (Lower Saxony, western Schleswig-Holstein, and the Bochum area of North Rhine Westphalia) are more heavily weathered and levelled ( Old Drift ) as the last large scale glaciations here occurred at least 130,000 years ago. The region

In the 17th century it was turned into a representative, but nevertheless defensible palace that was the northernmost example of the Weser Renaissance style. Its founder and builder was the noble family of von Bartensleben . After their line died out in 1742 the Wolfsburg was inherited by the counts of Schulenburg . The name Wolfsburg (literally "Wolf Castle") does not indicate that

1323-484: The edges of an Urstromtal may have been significantly altered by more recent processes, especially the thawing of dead ice blocks or the accumulation of sand dunes . In the post-glacial period , many Urstromtäler became bogs due to their low lying situation and the high water table. In Central Europe , there are several Urstromtäler from various periods. Some sections of the aforementioned main valleys have been given their own names. The Lusatian Urstromtal and
1372-423: The fortifications slighted. Six years later the von Bartenslebens had the fortifications rebuilt because they wanted to retain the military character of the castle. In the early stages around 1300 the Wolfsburg only had a stone tower house ( Wohnturm ) on the Aller, whose precursor may have been a wooden watchtower in the style of a lowland motte . The present, roughly 23 metre high tower, later designated as
1421-430: The grain size can vary considerably, however. Fine sand dominates especially in the upper sections of the Urstromtal sediments. The thickness of the Urstromtal sediments also varies a great deal, but is mostly well over ten metres. Urstromtäler have wide and very flat valley bottoms that are between 1.5 and 20 kilometres wide. The valley sides, by contrast are only a few to a few dozen metres high. The bottom and

Following the ice ages, rain-fed, raised bogs originated in western and northern Lower Saxony during warm periods of high precipitation (as influenced by Medieval Warm Period). These bogs were formerly widespread but much of this terrain has now been drained or otherwise superseded. The coastal areas consist of Holocene lake and river marshes and lagoons connected to Pleistocene Old and Young Drift terrain in various stages of formation and weathering. After or during

Today Urstromtäler are only partly used by rivers, because the majority have found shorter routes to the sea (like the Oder and Vistula ). The straight troughs of the Urstromtäler between the rivers were used for canal routes due to their low gradient, for example for

These are the Watchman's Tower ( Hausmannsturm ) which at around 30 metres is the highest, the Owl Tower ( Uhlenturm ) and the hexagonal Wendelstein tower with its circular staircase . They were built in the 16th century as the castle was converted into a palace. The north and south wings from the 16th century were mainly used for residential purposes. The roughly 25 metre high east wing

This wing of the building clearly shows how, by the end of the 16th century, the power of the von Bartenslebens was visibly demonstrated through their architecture. The reason for the construction of the Wolfsburg

In addition this area was protected by a curtain wall with defensive bastions or Rondellen , against which the later domestic buildings and stables, the present coach houses ( Remisen ) were built. Investigations in recent times revealed that the castle was not, as previously suspected, built on piles in boggy terrain. For
1715-538: The later castle, the bergfried acted as a dungeon and prison. Due to its situation in the Aller valley, the castle was probably surrounded by water from the outset. Certainly until the 19th century it was protected by two moats that were fed from the nearby Aller and the Hasselbach stream. The inner moat encircled the castle itself which, together with its drawbridges, made it a water castle . The outer moat surrounded
1764-436: The most part it stands on a sandy subsoil and only rests in places on oak piles. In the middle of the 15th century, a medieval castle no longer reflected the status of the von Bartenslebens. They turned the less comfortable building into a showy palace in the Weser Renaissance style with gardens and parks. Nevertheless, it retained the character of a fortified water castle until 1840, when the protective moats were filled in as

In the 20th century, the city built here in 1938 was named after Wolfsburg Castle. Initially it was called the Stadt des KdF-Wagens ("Town of the Strength through Joy Car") because of the industrial plant established to build

Later it was even equipped with cannon, for according to a 1437 document the number of guns was to be increased by 10 pieces in the event of war. According to this record, there were only attacks on the castle during the feud of the von Bartenslebens against Duke Otto of Lüneburg in 1464, whereby it

During the Cold War , in the event of war between NATO and the Warsaw Pact , NATO military strategists identified the North German plain as an area that could have been used for two of three major invasion routes into Western Europe by Warsaw Pact forces. The third route was the Fulda Gap further south. The North German plain routes were the best attack options for an attacking army. However,

The wolf that gave its name to the castle is a heraldic beast on the coat of arms of the von Bartensleben family who built the edifice. Their coat of arms comprises a leaping wolf above two sheaves of corn. The family brought

Human intervention caused the emergence of open heath such as the Lüneburg Heath , and measures such as deforestation and the so-called Plaggenhieb (removal of the topsoil for use as fertilizer elsewhere) caused a wide impoverishment of the soil ( Podsol ). The most fertile soils are the young marshes ( Auen-Vegen ) and

The lowest points are low moorlands and old marshland on the edge of the ridge of dry land in the west of Schleswig-Holstein (the Wilster Marsh is 3.5 m (11 ft) below sea level) and in the northwest of Lower Saxony (Freepsum, 2.3 m (7.5 ft) below sea level). The highest points may be referred to as Vistula and Hall glaciation terminal moraines (depending on

The Wolfsburg emerged from the Thirty Years' War as one of the few aristocratic castles that remained undestroyed. It was almost continuously garrisoned by troops of the warring parties, the last being the Swedes. The lords of Brunswick and Magdeburg forced their withdrawal came in 1650 by having the castellans have

As elements of the glacial series, Urstromtäler are intermeshed with sandur areas for long stretches along their northern perimeters. It was over these outwash plains that the meltwaters poured into them. Urstromtäler are relatively uniformly composed of sands and gravels ;

These knights also watched over the trade routes where they crossed the River Aller and that entailed the construction of a fortification to protect their lordship. The first definite record of the castle was in 1302 where it is referred to as the Wluesborch . The document
