Trips Castle was built in the 15th century and has a nearly square shape with a courtyard. The building has a two-story brick structure with a high substructure and an impressive seven-story tower with a capped roof on the western side. The corner towers still have partly intact corbels. The castle was modified in the 18th century, mainly around the courtyard and inside the buildings.
There are two gatehouses dating from the second half of the 17th century that connect to the main house. The inner gatehouse has a main gate in the north wing with a projecting gable. The building beside the gate was converted into living quarters for the tenant. On the south side of the main castle is a geometrically arranged garden with two summer houses from the 18th century.
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.
