Lochmaben Castle was originally a motte-and-bailey castle built south of the current castle in c. 1160 by the Bruce family, Lords of Annandale. King Edward replaced it with a much sturdier structure at the south end of Castle Loch around 1300 and its remains still show the massive strength of its defences. Archibald Douglas, Lord of Galloway, with the assistance of the Earls of March and Douglas, after a siege of nine days, took Lochmaben Castle from the English and 'razed it to the ground' in 1384.
Lochmaben Castle remained important and had a turbulent history until some time after the early 17th century by which time it had seen its last siege and was gradually abandoned. The castle is now protected as a scheduled monument.
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.
