Lochindorb Castle is a former stronghold of the Clan Comyn and is built on what now is said to be an artificially created island. The castle is first recorded during the Wars of Independence when Sir John ('the Black') Comyn died there in 1300. By 1455 the castle was in the hands of Archibald Douglas, Earl of Moray, The next year, after Douglas's defeat and death at Arkinholm, Lochindorb was again forfeited to the Crown and this time ordered to be slighted, the work of dismantling its defences being entrusted to the Thane of Cawdor. Since then, it has been left as a ruin.
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.
