Simiane-la-Rotonde has remained practically unchanged for centuries. On the hilltop stands the truncated cone-shaped edifice that gave Simiane-la-Rotonde its name: the keep, or rotunda, of the old Château des Simiane-Agoult. Built in the 12th century, its massive exterior is remarkable for its hexagonal shape. The interior, an uneven dodecagon, is especially splendid. It is a vast room with a series of arches topped by finely sculpted capitals. The ceiling has a stone cupola of 12 ribbed vaults towering five metres high. It is an amazing example of Romanesque architecture, both civil and military.
The southern wing of the castle has also been restored and you can visit parts of the main building and the fortifications. The rooms on the ground floor date from the Middle Ages and recount the castle's history. The upper floor, in Renaissance style, houses the Sainte Victoire Aromatherapy Laboratory, which offers workshops in essential oils to the public.The castle is also the magical setting for exhibitions and the international festival of early music Les Riches Heures Musicales de la Rotonde in August.
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.
