Cubbie Roo's Castle, built about 1150, is one of the oldest castles in Scotland and was mentioned in the Orkneyinga Saga. It takes its name from Kolbein Hruga who was said to have lived there. In King Haakon's saga, it is mentioned that after the last Norse Earl of Orkney, Earl John, was murdered in Thurso, his killers fled to Wyre. They took refuge in the castle, which was so strong that the besiegers had to thrash out a deal with them to get them out.
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.
