The manor was first mentioned in 1323 as Alba Curia. It was constructed as a vassal castle in the Middle Ages. In the 1620s-1630s, it was rebuilt as a Renaissance palace, and slightly altered in the 18th and 19th centuries. In the 20th century, the estate belonged to the Soviet military forces, and the main building remained in ruins after a fire in 1993. In 2000-2002, the ruins were looted (the side portals were stolen, and rear wall broken along with the lion mascaron of the main portal, among other things).

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.
