La Varde is an 11m long bottle shaped passage grave with 6 capstones and a small oval recess towards the rear. It dates back to Neolithic Age (3000-2500 BC). Originally covered by a mound 18m in diameter and a peristalith. The mound has been partially restored and two capstones are supported by modern pillars. Two layers of paving were recorded above and between which burnt and unburnt human bones, limpet shells and pebbles were found. Fragments of some 150 Neolithic and Early Bronze Age pots were also recovered as well as flint, stone tools, a serpentine ring, Gallo-Roman pottery, querns and fragments of bronze. The chamber had been sealed with a dry stone wall and also included a small slab lined cist set into the floor.
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.
