Corullón Castle dates from 15th century. Its tower was copied to build a similar one in Tuscany (Italy). Today, the tower and the surrounding ruins are still preserved. The best place which has been preserved is the Tower of Homage. On its entry point, two armorial bearings mark both houses, Osorio´s House and Valcarce´s House. It is a squared tower with three storeys, separated by imposts, battlements, modillions, meurtrières, and the remains of a great nave in tree sections. Its construction is from 15th century and it belonged to Alvarez Osorio until 1486, and then to Álvarez de Toledo.
Currently, the castle belongs to the Marquises of Villafranca´s descendants who restored it some years ago.
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.
