From the original Château de Loubens castle remains today the main 15th and 16th century building and three towers which still bear their original Renaissance design. The north facade, facing the park, is framed by two defensive round towers. The high west walls plunge into a pond, remains of the original moat. On the south side, the castle sunny terrace overlooks the surrounding countryside. An hexagonal tower embeded into the Renaissance main building brings rhythm to the facade.
The 10 acres around the castle have been redesigned using to the best the remains of its previous successive settings. The most ancient elements date from the Renaissance period. Among them, some remarkable box trees and 500 years old green oaks. A little parterre in classical French style on the north side leads to 4 squares of wild prairies framing a large alley planted with limetrees in 1825. Inside the grove, a stream, a bassin and a fountain bring animation and coolness into the woods.
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.
