Situated on a small wooded hill overlooking the village of Odrinhas, site of Roman ruins and an archaeological museum, it consists of about twenty menhirs and other monoliths or megaliths.

[1][2] The site, which is assumed to be a dolmen or cromlech, contains mainly cylindrical stones of varying heights, with the largest being approximately four metres tall.

The size of the stones decreased as they became more distant from the central menhir and the megaliths were arranged irregularly depending on the terrain.

No carved or painted symbols have been detected, except for a few pairs of small circular cavities, possibly representing eyes.

A small number of items have been found to the west of the complex, including flints from the Lower Paleolithic, ceramic fragments and other items from the Neolithic period, and ceramic fragments from the Iron Age, suggesting that the site has been reused over time.
