Castellar de la Frontera is a village within a castle surrounded by the walls of a well preserved Moorish-Christian fortress. It is located within the Parque Natural de Los Alcornocales next to a reservoir formed by the Guadarranque River.
The history of the village goes back to prehistoric times and the Bronze Age, after which the place became a medieval fortress. The prehistoric presence is still evident in the many caves around the area, where enthusiasts can see the wonderful cave drawings as proof of its heritage. It played an important role in the wars between the Spanish and the Muslims. In such a high up advantageous strategic position, peoples of many cultures wanted to control this strong vantage point.
The village was conquered and won back between Fernando III, the Moors and then Juan II, who described it as 'such a wonderful, strong town'. After the many battles of medieval times, by October 1650 Teresa María Arias de Saavedra, the Countess of Castellar, took possession of the town and later it was in the hands of the Medinaceli family.
The village was abandoned in the 1970s and its inhabitants moved to the aptly named Nuevo Castellar. The derelict state of the village attracted a number of Germans who took over the empty houses and built temporary dwellings outside the walls. The village was later repopulated.

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.
