Altenburg castle is perched on top of Bamberg's highest hill and is one of Bamberg's major landmarks. The castle was first mentioned in 1109 and was used at this time as a refuge. In the 14th and 15th centuries it served as a richly furnished residence for Bamberg's bishops, but was almost completely destroyed in 1553 by margrave Alfred Alcibiades von Brandenburg-Kulmbach in the second margrave war.
The only remains of the medieval construction are the 33 metre keep from the 13th century and parts of the surrounding wall. An iron basket hangs from the upper section of the tower which was used to send fire signals to Giechburg castle near Scheßlitz, 20km away.
In the Romance period, Altenburg was rebuilt. E.T.A. Hoffmann retreated to one of the wall towers in 1812, to which the 'Hoffmannsklause' restaurant in the new building of the former palace (1901/02) owes its name. The terrace commands a panoramic view of the episcopal town and the surrounding region.
The restaurant was formed after the takeover by the 'Altenburg club'. The premises were located as it is today in the cultivation of the gatehouse. The kitchen, a vaulted room was built in 1834. In the last quarter of the 19th Century the premises has been newly decorated. Lippel family took over the restaurant in 1972.
References:Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
