The site, on the western slope of the Hartberg north of Schankweiler, dates from around 3000 BC. It is the only Neolithic tomb of this type in Rhineland-Palatiate. It is a gallery grave, with two chambers, formed from sandstone slabs and blocks, the main chamber measuring around 2 by 1.2 metres (6 ft 7 in by 3 ft 11 in). The entrance to the tomb is an incomplete slab with part of a circular opening about 70 centimetres (28 in) in diameter. There is the lower half of a slab separating the main chamber and a poorly preserved antechamber. There were originally roof slabs, and the grave was probably once covered with a mound.[1][2][3]
There has been excavation of the site. Bones and pottery sherds were found in the tomb, and flint knives, flint arrowheads and pottery sherds were discovered outside; these suggested a date of about 3000 BC. There was a small beaker in the tomb, with "barbed-wire" decoration, of the early Bronze Age, suggesting that the site was in use, perhaps with interruptions, for around 1,000 years. A long stone stele was found in the tomb, which may have stood above the mound.[1][2][3]
Slabs from the tomb were later used in the early Iron Age to build a house nearby. During the Roman period or later there was quarrying from the rocky ground that forms the western wall of the tomb.[1][3]
