The town of Airvault is dominated by the castle Château d'Airvault built on a hill. In the Middle Ages, this strategic position made it an important part of the powerful defensive system of the town.
The castle was constructed on an earlier Gallic oppidum in the 11-15th centuries. It was besieged and conquered in 1207 by Philip II of France. On 3 October 1569, after the Battle of Moncontour which saw the victory of the Duke of Anjou (the future Henri III), Gaspard de Coligny who commanded the defeated Calvinists the burning of the castle in revenge for René Ysoré (son of Jean Ysoré) who contributed to his defeat. Burned, the castle was abandoned by its owners.
At the start of the 20th century, the owner constructed a house in the lower court and planned to destroy the castle to sell the materials.
The Château d'Airvault is considered as one of the rare remaining specimens of military architecture of the 11th century. From this time, there remains the enceinte with its two uncrowned towers and its keep whose well-preserved silhouette marks the urban landscape.
The 14th- and 15th-century buildings inside the enceinte replaced in the original buildings. Two quadrangular towers added obliquely to the corners of the enceinte on the ramparts are dated to the 13th or 14th century. The rectangular châtelet, defended by a bretèche and hoardings, is pierced by a door with a portcullis and murder hole giving access to the court.
The main dwelling of the 15th century is located along the west curtain wall. Among the outbuildings are the prison with its two vaulted cells lit by an arrowslit and a stable.
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.
