When Monturque Castle was exactly built is unknown. Archaeological findings suggests it was built during the reign of the Ummayad Caliphate (661–750 AD) on Roman remains.
The Castle was conquered by Ferninand III in 1240, and for a long time thereafter its ownership passed intermittently between the Crown and Nobility. One early record of this is from 1273, when half of the Monturque tower was awarded by Martin Sanchez to his grandson, Lope.
The well-preserved tower, Torre del Homenaje, stands in the center of the Patio de Armas. A sober and simple structure, this tower was the best equipped of the castle to house its guests, who would probably only spend short stays here, as it does not show signs of having been adapted for permanent accommodation. The castle and tower are located on Calle de Rafael de Lara.
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.
