Starhrad castle was built to protect the old road leading Povazie and it was first mentioned in 1267. The oldest part of the castle was the tower. In the 14th century the castle was in royal hands and some houses and farm buildings were built. Since 1443 it belonged mostly to the Pongracovce family. In the 16th century Starhrad was abandoned and left to decay. By the beginning of the 18th century there lived only guards. During the Second World War German troops fought against the local partisans in the castle area.
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.
