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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
