The Castle of Fadrell is located in the municipality of Castellón de la Plana. It is a castle of Muslim origin, built between the 11th and 13th centuries.
The castle, with an irregular shape, consisted of four enclosures that adapted to the terrain in a stepped manner. In the upper enclosure is the Alcazaba with three semicircular towers, along with remains of walls and cisterns.
The intermediate enclosure, Albacar, which contains the former, has three more towers and houses the Hermitage of La Magdalena.
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.
