Krevo Castle is one of the oldest Belarus castles and dates from the early 14th century. It is an important place in Belarus because it was the first all-stone castle to be built in the region. The stone walls were 2.5m thick and 13m high. The castle had two towers which guarded the rest of the fortress. Grand Duke Keistut was murdered in the castle in 1381, and in 1385 the famousKrevo Union (between Poland and the Grand Duchy of Lithuania) was signed here.
During the 16th century the Tatars and the Russians tried to capture the castle but it remained intact. By the early 19th century the castle was abandoned and the buildings were mostly destroyed during World War I. Today only the ruins of the castle remain. The perimeter walls can still be seen, but only a few fragments of the towers are still intact. There is a magnificent view of the ruins from the top of nearby Yuryeva Mountain.
Many legends surround the Krevo Castle ruins, including tales of an underground tunnel from the castle to Vilnius, and a beautiful princess who was bricked up alive in the castle walls. There is a pagan temple on Yuryeva Mountain and 1 of 4 amulet boulders, which used to lie at the entrance of Krevo to protect the town against trouble and disease, still remains.

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.
