Le Déhus is a fine Neolithic bottle shaped Passage Chamber with four side chambers off the entrance passage. Today there are six side chambers but two were erronously constructed during restoration. Side chamber first on the right was found to contain the bones of two individuals, kneeling side by side and facing in opposite directions, their bodies being supported by tightly packed earth and shells.
The sixth capstone, originally supported by a granite pillar has the engraved depiction of a male, 'Le Gardien du Tombeau'. Eyes, mouth, beard, hands, bow and numerous other symbolic shapes can be seen with the use of oblique lighting.A large quantity of finds were recovered during excavtion. Cremated human remains, pottery, a stone axe, a copper dagger and vast quantities of limpet shells. Evidence of re-paving showed that the chamber was in use for a considerable period of time. The whole tomb is covered by a mound with a peristalith made of large stones and dry-stone walling.
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.
