At an elevation of 438 meters on the Cresta del Gallo Sierra, Castillo de La Luz is an 9th century construction built by the Moors. The castle was part of Murcia's defense buildings and a check point between the coast and the city. A tank, and parts of a wall and a tower, still stand. It was abandoned in the 13th century after Murcia was merged to the kingdom of Castilia.
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.
