The old Dalquharran Castle consists of a ruined 15th-century tower, with a round tower at one corner. It was extended to form an L-plan, and rises to three storeys and a garret within the corbelled-out crenellated parapet. The castle was extended and altered in the late 17th century, and was surrounded by gardens and landscaped grounds. The basement is vaulted.
In the 18th century, when it was abandoned for the mansion of Dalquharran New Castle. Today the ruins of the old castle are reachable via public footpaths along the riverside, and although the castle is labelled dangerous, there is evidence of it regularly being used as a drinking den.
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.
