Gars am Kamp Castle was built around 1120-1130. The heterogeneously arranged complex of the hilltop castle stands on terraced land descending in three levels by the Kamp River.
On the highest level stands the main castle, enclosed by a ring wall. On the second, middle plateau, there are the southern gate tower and the castle chapel, a hall building from the 16th century to the west, and the surrounding fortifications from the 13th century. On the third, lowest level, connected by a castle path, the fortified outer bailey hosts the parish church of Thunau am Kamp on a southern terrace. A small coat of arms stone of the Rotthal family (dated 1709) is located above the portal to the north tower.
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.
