This extraordinary collection is located on a plateau near the SE end of the Onyi Mountain . In this place we find 4 cromlechs, a double chamber, a monolith and two structures of undefined characteristics. The materials are sandstone and terrain conglomerates. The whole collection was excavated by J. Peñalver in 1983-1985 and reconstructed later.
The biggest cromlech is 5.60 meters in diameter and is made up of 31 stones, among which one that mentions mention measuring one and a half meters high.
Another cromlech, 4.80 meters in diameter, includes 18 stones, two of which are also almost a meter and a half in height.
The group also includes an isolated monolith that is similar in height to the other ones.
