The Château de Hohbarr (Haut-Barr) is a medieval castle, first built in 1100, above the city of Saverne in what is now the French département of Bas-Rhin. It was built on sandstone rock 460m above the valley of Zorn and the plain of Alsace. Because of this, it has been called the eye of Alsace.
The current castle was built in 1583 by Jean de Manderscheid. The Peace of Westphalia mandated the destruction of several castles, including Hohbarr, but after the beginning of the War of the Spanish Succession, in 1701, the fortress was back in use. It was abandoned around 1770, but the vault continued to be occupied until the French Revolution.
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.
