Hohentwiel
Hohentwiel is an extinct volcano in the Hegau region of Baden-Württemberg in southern Germany The mountain is west of the city of Singen and 20 miles (30 km) from Lake Constance. Hohentwiel began forming, along with the chain of volcanoes in the Hegau region, about 7–8 million years ago, when a layer of volcanic ash and stone was laid down. The magma consists of phonolite. In the following millions of years, the core was opened 260 metres beneath the surface by the glaciers from the ice age. This formed the core that is now exposed, after the ensuing millions of years of erosion. Hohentwiel Castle, whose ruins are on top of Hohentwiel, was built in 914 using stone taken from the mountain by Burchard II, Duke of Swabia. Originally, the Monastery of St. Georg was within the fortress, but in 1005 it was moved to Stein am Rhein (now in Switzerland), and the Swabian dukes lost control of Hohentwiel. In the later Middle Ages the noble families von Singen-Twiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hohentwiel Castle
Hohentwiel Castle is a ruin of a former castle on the peak of the dead volcano Hohentwiel. It is located in the region called Hegau, which is close to the Lake of Constance. The mountain overtowers the city of Singen, which is located on the foot of the mountain, by 260 meters. With an overall area of nine hectares, Hohentwiel castle is the biggest castle ruin in Germany which is open for tourists. Since 1990, more than 80,000 tourists have visited the ruin every year; the maximum was reached in 2002 when 126,500 people visited Hohentwiel castle. The annual Hohentwiel-Festival takes place in the fortress area. In its history, the castle was also a ducal seat during the Early Middle Ages and an ordinary castle during the High Middle Ages. The fortress on the Hohentwiel was first mentioned in 915. In the following times, the mountain was in possession of different noble families, such as the House of Zähringen. In the early 16th century, the Hohentwiel was more and more influenced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Singen
Singen (Low Alemannic German, Low Alemannic: ''Singe'') is an industrial city in the very south of Baden-Württemberg in southern Germany and just north of the German-Swiss border. Location Singen is an industrial city situated in the very south of Baden-Württemberg in Germany close to Lake Constance just north of the German-Swiss border and is the most important city in the Hegau area. Landmarks The most famous landmark of Singen is Hohentwiel, a volcanic stub on which there are the ruins of a fortress destroyed by French troops during the Napoleonic Wars. World War II 'Singen route' Singen is notable in military history for the Singen route in World War II. This route into Switzerland was discovered by Dutch naval lieutenant Hans Larive in 1940 on his first escape attempt from an Oflag (prisoner's camp for officers) in Soest. After being captured at the Swiss border near Singen, the interrogating Gestapo officer was so confident the war would soon be won by Germany that he t ...

Hegau
The Hegau is an extinct volcanic landscape in southern Germany extending around the industrial city of Singen (Hohentwiel), between Lake Constance in the east, the Rhine River in the south, the Danube River in the north and the Randen—as the southwestern mountains of the Swabian Jura are called—in the west. It was first mentioned in A.D. 787 in the Latinised form ''in pago Egauinsse''.Albert Krieger: Topographisches Wörterbuch des Großherzogtums Baden, Vol. 1, p. 882 (1904)' The most famous sight of the Hegau is the Hohentwiel Hohentwiel is an extinct volcano in the Hegau region of Baden-Württemberg in southern Germany The mountain is west of the city of Singen and 20 miles (30 km) from Lake Constance.

Lake Constance
Lake Constance (german: Bodensee, ) refers to three Body of water, bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein, Lake Rhine (''Seerhein''). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria, the Swiss cantons of Canton of St. Gallen, St. Gallen, Canton of Thurgau, Thurgau, and Canton of Schaffhausen, Schaffhausen, and the Austrian state of Vorarlberg. The actual location of the border Lake_Constance#International_borders, is disputed. The Alpine Rhine forms in its original course the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Phonolite
Phonolite is an uncommon extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite rather than quartz. Its intrusive equivalent is nepheline syenite. Phonolite is typically fine grained and compact. The name ''phonolite'' comes from the Ancient Greek meaning "sounding stone" due to the metallic sound it produces if an unfractured plate is hit; hence, the English name ''clinkstone'' is given as a synonym. Formation Unusually, phonolite forms from magma with a relatively low silica content, generated by low degrees of partial melting (less than 10%) of highly aluminous rocks of the lower crust such as tonalite, monzonite and metamorphic rocks. Melting of such rocks to a very low degree promotes the liberation of aluminium, potassium, sodium and calcium by melting of f ...

Stein Am Rhein
Stein am Rhein (abbreviated as Stein a. R.) is a historic town and a municipality in the canton of Schaffhausen in Switzerland. The town's medieval centre retains the ancient street plan. The site of the city wall, and the city gates are preserved, though the former city wall now consists of houses. The medieval part of the town has been pedestrianised and many of the medieval buildings are painted with frescoes. History In or around 1007 Emperor Henry II moved St George's Abbey from its former location on the Hohentwiel in Singen to Stein am Rhein, at that time little more than a small fishing village on the Rhine. This was in order to strengthen his presence at this strategic point where major road and river routes intersected. He gave the abbots extensive rights over Stein and its trade so that they could develop it commercially. In this they were very successful, and Stein am Rhein rapidly became a prosperous town which in the 15th century was briefly granted '' reichsf ...

Hans Müller Von Bulgenbach
Hans Müller, also known as Hans Müller von Bulgenbach, (c.1490 – 12 August 1525 in Laufenburg, Switzerland, Habsburg-Laufenburg), was a peasant leader during the German Peasants' War. After a career in the French military, he played a pivotal role in the initial peasant uprising at Stuhlingen, and organised peasant bands throughout southwestern Germany. He was captured after the peasants' loss at Klettgau in July 1525, imprisoned at the Hohentweil fortress, and executed in August of that year. Participation in the German Peasants' War The exact date of his birth is not known, but is probably between 1485 and 1495. The location of his birth is usually given as the village of Bulgenbach, which today is in the vicinity of Grafenhausen, near the Black Forest lake of Schluchsee. Müller entered the imperial military service and fought in France. After he returned to his homeland, in the territory of the Stühlingen count, he was caught up in peasant uprisings in 1524. In June, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baden-Württemberg
Baden-Württemberg (; ), commonly shortened to BW or BaWü, is a German state () in Southwest Germany, east of the Rhine, which forms the southern part of Germany's western border with France. With more than 11.07 million inhabitants across a total area of nearly , it is the third-largest German state by both area (behind Bavaria and Lower Saxony) and population (behind North Rhine-Westphalia and Bavaria). As a federated state, Baden-Württemberg is a partly-sovereign parliamentary republic. The largest city in Baden-Württemberg is the state capital of Stuttgart, followed by Mannheim and Karlsruhe. Other major cities are Freiburg im Breisgau, Heidelberg, Heilbronn, Pforzheim, Reutlingen, Tübingen, and Ulm. What is now Baden-Württemberg was formerly the historical territories of Baden, Prussian Hohenzollern, and Württemberg. Baden-Württemberg became a state of West Germany in April 1952 by the merger of Württemberg-Baden, South Baden, and Württemberg-Hohenzollern. The ...
