The Château de Peyrelade name is derived from the occitan 'Pèira Lada', meaning wide rock; an accurate description of the site. Objects found on the site suggest it was inhabited in prehistoric times.
Thanks to its position controlling the entrance to the Gorges du Tarn, it was one of the most important castles in the Rouergue province. It existed at least as far back as the 12th century, and was the scene of incessant battles and sieges until 1633 when it was dismantled on the orders of Richelieu.
The ruins give a good idea of the layout of the castle. The outer wall was more than 250m long, 10m high and 2.1m thick. The castle was dominated by a natural rock keep more than 50m high, only accessible from a round tower attached to it.
The Château de Peyrelade is one of a group of 23 castles in Aveyron which have joined together to provide a tourist itinerary as La Route des Seigneurs du Rouergue. Château de Peyrelade is open to visitors from mid-June to mid-September.
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.
