Colombier Castle was built in the 11th or 12th century as a fortified tower over the ruins of the Roman villa. It expanded in the 13th Century and by the 16th century had reached its present appearance.
One of the largest Roman era villas in Switzerland was excavated from under the castle in 1840-42 by Frédéric Dubois de Montperreux. It was built in multiple stages between the 1st and 3rd centuries AD into a palatial mansion with a peristyle, at least two baths with mosaics and frescoes and terraced gardens.
In 1806, Colombier Castle was converted into a military hospital. Starting in 1824 it was used by the Federal militias as a parade ground and was converted into a barracks and given an expanded arsenal. In 1877 it became the official barracks of the 2. Division, which later became Field Division 2. In 2003, the Army XXI reforms dissolved the Division and in 2004 the barracks became an infantry training center.References:
Bamberg is located in Upper Franconia on the river Regnitz close to its confluence with the river Main. Its historic city center is a listed UNESCO world heritage site.
Bamberg is a good example of a central European town with a basically early medieval plan and many surviving ecclesiastical and secular buildings of the medieval period. When Henry II, Duke of Bavaria, became King of Germany in 1007 he made Bamberg the seat of a bishopric, intended to become a 'second Rome'. Of particular interest is the way in which the present town illustrates the link between agriculture (market gardens and vineyards) and the urban distribution centre.
From the 10th century onwards, Bamberg became an important link with the Slav peoples, especially those of Poland and Pomerania. During its period of greatest prosperity, from the 12th century onwards, the architecture of this town strongly influenced northern Germany and Hungary. In the late 18th century Bamberg was the centre of the Enlightenment in southern Germany, with eminent philosophers and writers such as Georg Wilhelm Friedrich Hegel and E.T.A. Hoffmann living there.
Bamberg extends over seven hills, each crowned by a beautiful church. This has led to Bamberg being called the 'Franconian Rome'.
