Carn Ban is a Neolithic chambered tomb located on the Isle of Arran. It is considered as one of the most famous of the Neolithic long cairns of south-west Scotland. It is of a type found across south-west Scotland known as a Clyde cairn. It is trapezoidal in shape, with a semicircular forecourt at the upper northeast end. The forecourt has an entrance leading into a long chamber divided into compartments by cross-slabs, similar to the arrangement at Torrylin Cairn, about 3 miles to the southwest. The chamber of Carn Ban is 30 metres long and 18 metres broad. The tomb was excavated in the late 19th century, but the only finds were a flint flake, an unburnt fragment of human bone, and a pitchstone flake.
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.
