The Ducal Palace of Béjar was built after 1203 by Alfonso VIII. Although these already very reduced in the XIXth century, they still conserve some square and round towers and part of their perimeter bordering the oblong hill on which the old part is based. Béjar was a royal place, but with Enrique III, in 1396, it passed to the lordship of Diego López de Zúñiga or Estúñiga, whose successors will hold the title of dukes of that place, granted by the Catholic Monarchs.
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.
