Castle da Rocha Forte was built by Archbishop Juan Arias around 1240 and has since served as an archbishop's and cabildo's residence, witnessing much of the medieval history of Santiago. In the year 1255 appears the first documentary mention of the fortress in relation to the capitular constitutions of Juan Arias. The castle was situated in a strategic location by road from Padrón village to Santiago. Pilgrims followed that route from Portugal.
In addition to its purpose for defence, the castle was also a home for the Archbishop, which could provide the men of the local church a shelter from rioting citizens. In 1317, Berenguel de Landoira was nominated as Archbishop. The residents did not like him and started a rebellion. Archbishop Landoira had all the leaders of the rebellion executed. In the 15th century in Irmandiño wars the castle was damaged badly and it was abandoned. Later, in 1472 the walls were dismantled. During the Franco era the ruins were used as a hideout. In 1962, an electricity pylon was installed to the castle area.
Since 2001, a series of archaeological excavations have been carried out, thanks to an agreement between the City Council of Santiago and the University of Santiago de Compostela, in order to recover the deposit and consolidate it by means of the creation of an Archaeological Park.

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.
