Barpa Langass is a Neolithic chambered cairn, which now survives as a massive pile of stone. It is located on a hill overlooking a dramatic landscape of barren peatland. The cairn is roughly 16 feet high, and around 82 feet across. The inner chamber is still accessible. From the east side of the tomb the narrow passage leads to a wide chamber. It is difficult to judge the original appearance of the cairn, but it has been suggested that it had a more bun like appearance with outer facing stones and an earthen top portion. This great cairn is the only chambered cairn in the Western Isles with its chamber still roofed over. During excavation in 1911 traces of burnt burials, beaker shards, an arrowhead and a disc of mica (maybe a pendant) were found. On the south side of the same hill is Pobull Fhinn an ancient stone circle.
At the time the cairn was built the Western Isles had a much milder climate, the peat bogs were not yet formed, and the landscape would have been more like southern scrubland and woodland. It would have been capable of providing pasture for grazing animals. Barpa Langass stands on the north side of Beinn Langais, and just half a mile from the stone circle of Pobull Fhinn To find this grand cairn travel to North Uist and it is signposted off the A867 Lochmaddy-Clachan road.
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.
