Simple dolmen
Neolithic megalithic tomb
This megalithic tomb consists of a chamber formed by one stone on each side and a capstone. This type of tomb is known as a simple dolmen. The tomb was constructed between 3500 and 3300 BC, making it one of the oldest megalithic tombs in the region.
Normally, when constructing simple dolmens, a low stone was used on one of the narrow sides, as this is where the entrance to the burial chamber was usually located. In the case of this particularly massive tomb, however, a short, sloping entrance was built into one corner of the burial chamber.
The burial chamber, with internal dimensions of approx. 2 x 1.2 m, and the passageway were originally embedded in a round mound of earth and boulders.
The excavation carried out in 1967 as part of a research project on megalithic tombs revealed that, after its initial occupation, the tomb was repeatedly used for secondary burials.
