Built in the 13th century by the lords of Poudenas, vassals of Edward I Plantagenet, Duke of Aquitaine and King of England, the Château de Poudenas defended the valley of the Gélise, overlooking it by 50 meters, at the opening of the Landes Forest.
A military fortification until the 16th century, the castle was then adorned with mullioned windows, opening the keep to the north and south. A hundred years later, a complete redesign adorned the inner courtyard with two terraces each supported by four arcades, and the main facade with a triple gallery reminiscent of an Italian villa and its landscape.
The monument has been classified as a historic monument since August 22, 1984, for its facades and roofs of the keep and the buildings surrounding the main courtyard, its south facade with its gallery and terraces, its corresponding roof, its terrace in front of the castle facade, its stone staircase with straight flights, its fireplace in the grand salon and reception room, and its surrounding wall. It has also been listed since May 26, 1952, for the rest of its facades and roofs.
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.
