Vipava Castle was built by the Patriarchate of Aquileia and first recorded in 1275 as Castrum Wipaci superioris. It was the residence of the knights of Vipava until the mid-14th century, when it became a ducal fief, granted to a long series of noble and knightly families, including the knights of Rihemberk, lords of Snežnik and Belopeš, Counts of Celje, barons Herberstein, Counts Thurn, the noble family of Edling, counts Thrillegkh, and finally the counts Lanthieri, who abandoned the decaying castle in the 17th century.
The ruins of the Romanesque structure trace the rectangular layout of its thick walls, enclosing two residential buildings guarded by an impressive defensive tower.
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.
