Auchagallon Stone Circle is the remains of a Neolithic or Bronze Age burial cairn, surrounded by a circle of fifteen stones. The cairn and stone circle is situated on a slight ledge of a west-facing slope, overlooking Machrie Bay. The circle comprises fifteen blocks varying in height from 0.5 metres to 2.3 metres. The stones are of red sandstone, except two which are a pale grey granite. The circle has a maximum diameter of 14.5 metres.
In the centre is a large stone cairn. Antiquarians digging here in the 19th century found a burial cist in the centre, although there are no records of any other remains. Although the monument is now called a stone circle, it was probably built as a kerbed cairn.
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.
