There has been a castle at Glenarm since the 13th century, where it resides at the heart of one of Northern Ireland's oldest estates. The present castle was built by Sir Randal MacDonnell, 1st Earl of Antrim, in 1636, and it has remained in the family since its construction. It is currently owned by Randal, Viscount Dunluce, the son of Alexander McDonnell, 9th Earl of Antrim. The McDonnells have been in Glenarm for nearly 600 years and the Estate has been in the family for 400 years.
The Castle's Walled Garden is open to the public between May and September and hosts many events.
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.
