Five steles were identified, four of which were in situ, and their shoring was made by slabs with dimensions larger than those delimiting the chamber.
The tumulus had a sub-elliptical form about 6 / 7.2 meters in diameter, consisting of slabs and stony blocks arranged in a sometimes chaotic form, being found to close this heap of stones a locking ring constituted by elements large stones.
