The place dominated by the Ucero castle has been inhabited since prehistoric times. The castle is built on the site of an ancient Celtiberian castro. The site was first time mentioned in 1157 when Alfonso VII located the village of Sotos the Suso between Uxama and Ucero and there are documents that indicate that the castle already existed in the 13th century. It is estimated that the important hermit of San Juan de Otero, nowadays destroyed, was ubicated near San Bartolomé, which was a Templarian chapel.
References: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.
