The Château de Murs, perched on the heights of Murs near the Vaucluse mountains, was built between the 12th and 18th centuries.
The oldest remains, dating back to the 12th century, were built by the d'Agoult family as a fortified garrison with ramparts and a tower, now located in the western part of the current castle. Around the same time, a village church served both as a chapel and parish, featuring a small cloister.
In the 13th century, the 'Maison Crillon' was built as a residence for visiting lords. In 1462, the property was transferred to the Astouaud family, who expanded and refined the castle, adding a central keep with a chapel and justice hall. In the Renaissance period, they built a new house beside the Maison Crillon.
In the 18th century, Jean-Baptiste François d’Astouaud, Marquis of Murs, added gardens and a grand iron gate bearing the family coat of arms. By the French Revolution, the castle had fallen into neglect.
Restoration began in the mid-19th century, led by the Vayson family. The poet and artist Paul Vayson, a descendant, described the castle’s haunting beauty, with its ivy-covered walls, crumbling battlements, and nesting swallows.
Complete restoration was achieved in the mid-20th century. Today, the castle remains private and is not open to the public.
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.
