Located in the extreme north of the province of Segovia, Fuentidueña village rises above a narrow valley formed by the Duratón River, a unique geographical location that explains the importance of the town during the Middle Ages. The Villa was walled on its north, south and west sides with a clearly defensive function. On the other hand, there is an impressive rock cut that makes defense very easy. Intramural access is only possible through one of its three doors.
There is no historical facts about the origin of castle, but it seems that its construction dates back to the 12th and 13th centuries. It had importance with the reign of Alfonso VII, who had Cortes here and peace was concluded with Navarra and granted testament in 1204.
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.
