Vaduz Castle is the palace and official residence of the Prince of Liechtenstein. The castle gave its name to the town of Vaduz, the capital of Liechtenstein, which it overlooks from an adjacent hilltop. The erstwhile owners - presumably also the builders - were the Counts of Werdenberg-Sargans. The Bergfried (keep, 12th century) and parts of the eastern side are the oldest. The tower stands on a piece of ground some 12 x 13 metres and has a wall thickness on the ground floor of up to 4 m. The original entrance lay at the courtyard side at a height of 11 metres. The chapel of St. Anna was presumably built in the Middle Ages as well. The main altar is late-Gothic. In the Swabian War of 1499, the castle was burned by the Swiss Confederacy. The western side was expanded by Count Kaspar von Hohenems (1613–1640).
The Princely Family of Liechtenstein acquired Vaduz Castle in 1712 when it purchased the countship of Vaduz. At this time, Charles VI, Holy Roman Emperor, combined the countship with the Lordship of Schellenberg, purchased by the Liechtensteins in 1699, to form the present Principality of Liechtenstein. During the medieval days of the principality, the prince could have sought refuge in the castle from a potential peasant uprising.
The castle underwent a major restoration between 1905 and 1920, then again in the early 1920s during the reign of Prince Johann II, and was expanded during the early 1930s by Prince Franz Joseph II. Since 1938, the castle has been the primary residence of Liechtenstein's Princely Family. The castle is not open to the public as the princely family still lives in the castle.
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.
