Dun Telve is one of the best preserved Iron Age brochs in Scotland. The neighbouring broch of Dun Troddan lies 470 metres to the east, and the 'semi-broch' known as Dun Grugaig is around 2.5 kilometres further east.
Dun Telve is over 20m in diameter and the portion that still stands is about 10m high. Behind the narrow, west-facing entrance doorway, a 5m-long passage leads into the interior.
Along the passage is a small side-chamber, sometimes called a ‘guard cell’. The door (now missing) within the passage was well secured by a bar hole in the wall, just as in a medieval castle.
The section left standing gives a perfect cross-section to show how brochs were constructed. The two concentric drystone walls are tied together by large horizontal slabs. These slabs also form the floors of the narrow galleries between.
Access up the tower is by a winding stone stair, and openings at intervals once gave access to the upper floors. The presence of two horizontal stone ledges, or scarcements, up the height of the surviving section suggests that there were two upper floors. The top floor would have been around 9m above ground level.
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.
