Château de Cambiaire was built in the 14th century in the town of Saint-Étienne-Vallée-Française. It is a quadrangular building with a round tower at three of its corners and a square tower at the northwest corner. It consists of three wings around a courtyard on the west side by a battlements surrounding wall pierced by a gate. The great crenellated tower, which dungeon office, is crowned on its summit terrace of a watchtower with a roof shaped pepper shakers. This square building built shale stone mixed with white quartz is the oldest. It has three levels, the first two date from the 14th century, the last level and the spiral staircase from a raising of the late 15th century.
This tower seems more ostentatious than most military as much as the castle was never the castle of Saint-Etienne. One of the ground pavement dwelling is probably contemporary dungeon. The others are the result of rearrangements of the modern era and those of the late nineteenth century and finally repairs arising out the 1944 fire. A park of chestnut trees and cedars surrounds the castle. There is a replica of the Lourdes grotto and a chapel dating back to 1875 in neo-Gothic style.
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.
