The Château de Meung-sur-Loire, located next to the collegial church, was the country residence of the Bishops of Orléans. It was built and destroyed several times. The oldest still existing parts date from the 13th century and were built by Manassès de Seignelay (bishop from 1207 to 1221). Still standing are the main rectangular plan building, flanked by three towers, a fourth having been destroyed.
During the Hundred Years' War, the building was transformed into a fortress; it was taken from the English by Joan of Arc on 14 June 1429. At the end of the 15th century and start of the 16th century, building to the north incorporated a tower with drawbridge. The castle was abandoned from the Wars of Religion until the start of the 18th century, when Bishop Fleuriau d'Armenonville undertook the transformation of the structure into a comfortable residence.The rear façade was rebuilt in the Classical style by d'Armenonville. Beneath the castle are dungeons, a chapel and various medieval torture instruments, including one used for water torture.
In the middle of the 18th century, a wing was added to the southeast with a staircase serving the upper floors of the wing. In 1784, the chapel was built in the Neoclassical style, with sculpture by Delaistre. The two pavilions in the grounds are contemporary with this chapel.
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.
