There are the remains of an Irish round tower on the edge of the Armoy village. An early monastery was founded about AD 460 by Saint Olcán, a disciple of Saint Patrick. The only trace of an early monastery is the stump of the round tower, which stands in the grounds of St Patrick's Parish Church. The tower is about 11 m high and has three storeys. At one time, Armoy was the main religious settlement in the Irish part of the kingdom of Dál Riata.
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.
