Luna castle dates from the 13th century and was built under control of 'Guzmán the Good' upon a fortified convent of ribat or Muslim origin, in the 11th century. It is rectangular with five crenelated towers, and its interior is structured around a central courtyard.
Property of the Dukes of Arcos, the Ponce de León used the castle as a residence and there is evidence that the Catholic Monarchs visited the city and stayed there.
The Luna Castle is a symbol in itself for citizens of Rota, Cadiz, and proof of this is its presence on the coat of arms of the village. It has housed a hospital and a school, and is currently the location of the City Hall of Rota.

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.
