In the 13th century, the Lords of Wiltz built a fortified castle on a rocky promontory, initiating the development of the upper town of Wiltz. In 1388, the French attacked the town and burnt the castle down but it was soon repaired. In 1453, Wiltz was again attacked, this time by the troops of Philip of Burgundy. The round Witches' Tower to the east of the gardens is the oldest part of today's castle. Under Count John VI of Wiltz, the construction of today's Renaissiance style castle was begun in 1631. After delays caused by the Thirty Years War, the main building was not completed until about 1720. The old chapel was finished in 1722 and the monumental staircase leading down to the gardens was completed in 1727. The castle premises were acquired by the State of Luxembourg in 1951 for use as an old people's home.
Since 1953, Wiltz Castle has been the venue of an international music festival attracting artists and orchestras of international repute. Since 1999, the castle's stables have housed the National Museum of Brewing. The museum traces the history of beer production over the past 6,000 years, especially more recent developments in Luxembourg. The little tanning museum (Musée de la Tannerie) presents the history of the leather industry in Wiltz which dates from 1644.
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.
