Randeck Castle is a ruined hill castle on the Schlossberg west of the wine growing village of Mannweiler-Cölln. The castle was probably built in the 12th century. It is first recorded in 1202 with a Henry of Randeck (Henricus de Randeke). He was probably a grandson of Ulrich of Wartenberg.[1] He was succeeded in 1231 by his son Godfrey I of Randeck. The grandson of Godfrey in 1298, Dietrich of Randeck. Another grandson in 1311, George of Randeck. From here were also descended Eberhard of Randeck (d 1372), cathedral dean and Bishop-elect of Speyer.
The castle was loaned in 1649 by Emperor Ferdinand III to the Teutonic knight, Hans Ludwig of Lewenstein. After the Lewensteins died out, the castle fell in 1668 to the Electoral Mainz chancellor, Nikolaus Georg Reigersberg. In 1690, during the War of the Palatine Succession, the castle was suddenly stormed by the French and blown up. Despite that, a few of its buildings were made habitable again. It was reported in 1844 that the castle was in private hands; it was torn down and its materials utilised.
Today, the castle is owned by the Cultural History Society of Mannweiler-Cölln. The remains of the enceinte, a corner outwork, the flanking towers and the foundations of the bergfried have survived.

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.
