Arnot Tower is a ruined 16th-century castle. The current building dates from c. 1507, though fortifications were present c. 1400. The castle has four storeys and a vaulted basement. It was built by the Arnot family who have records dating back to 1105. David Arnot of Fyfe was one of 2000 noble landowners required to swear allegiance to King Edward I of England in 1296. Nicol Arnot Arnot was a loyal supporter of King Robert the Bruce. Robert Arnot was killed in the battle of Flodden in 1514. The Arnots abandoned the old tower around 1700.
In 1760 local poet Michael Bruce wrote a poem about the true story of a love affair between an Arnot daughter and a Balfour of nearby Burleigh Castle. The families were in a feud, and it is believed the daughter of Arnot eloped to Burleigh Castle.
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.
