Beaghmore is a complex of early Bronze Age megalithic features, stone circles and cairns. The site was discovered by George Barnett in the late 1930s during peat cutting when 1,269 stones were uncovered, and partially excavated in 1945–1949 when it was taken into state care. It was also excavated again in 1965. Hearths and deposits of flint tools were discovered and have been carbon dated to 2900-2600BC. Several of the stone rows run over the tumbled walls of field structures which also date from the Neolithic period. Excavation of one of the cairns revealed a polished porcellanite axe, which may have originated from the Tievebulliagh axe factory, some 70 miles away in County Antrim. The largest cairn featured a central pit containing an oak branch.
There are seven low stone circles of different sizes, six of which are paired, twelve cairns and ten stone rows. The circles are between 10 and 20m in diameter, and are associated with earlier burial cairns and alignments of stone rows lead towards them. The stones are small with few more than 0.5m in height and the circles are distorted, suggesting they are related to kerbs surrounding some megalithic tombs. A typical feature of the stone rows is a high and low arrangement where short rows of tall stones run beside much longer rows of small stones. The stone rows radiate from the circles in a roughly north-east direction.
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.
