Château de Parthenay was built during the 13th century whose remains are still visible to this day. The castle was built on a rock by the side of the river. A citadel was built around the castle which was only accessible through the Saint Jacques gate. The gate and the city walls are still largely intact. There is another gate at the other side of the city, the Tour de l'Horloge gate. Both gates have characteristic almond-shaped towers. In total, the citadel has over 30 defensive towers, 4 entrance gates and a defensive wall with a length of over 1km.
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.
