Loch Na Berie is the site of an Iron Age Broch and associated causeway. The site was excavated in the 1980s, which identified that the Broch had survived to first floor level. Loch na Berie is roughly 16.5 meters in diameter and the walls are roughly 3 meters thick. A modern causeway made of stones robbed from the broch was built to the west of the broch, though it is thought that an ancient causeway underlies the modern one.
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.
