The first hill fort overlooking the valley of Wolfach was built by Count Rapoto I von Ortenburg around 1120. Due to the power of Ortenburg house there were many conflicts with neihgbor states in the late 12th century and early 13th century. The castle was destroyed in one of these wars in 1192 and subsequently rebuilt. The medieval castle was sacked and almost completely destroyed in Landshut War of Succession in 1504.
The current Ortenburg castle was built in its current form as a renaissance castle in 1562. The interior furnishing of the halls had been first completed in 1800. Therefore, the castle holds interior decoration and art dating back over the course of two centuries. The precious coffered ceiling of the castle chapel is particularly worth noting. The ceiling, which had been made with five different types of wood, is among the most significant renaissance wood ceilings in Germany. Further art treasures included the knights’ hall and the renaissance inner courtyard. Today, the castle is home to the Ortenburg Castle Museum.
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.
