Cromelech composed of about fifty-five monoliths, mostly with small dimensions and many of them of irregular ovoid shape. It is not known, satisfactory, the original plant of the monument; the only case in which the structures were fully identified deployment is that of menhir 1, interpreted as menhir central enclosure.
The Xarez falls in immediate terms, in an area – the Lower Xarez – wich is very rich in traces of Neolithic habitat, scattered around the most prominent granite outcrops. In the limit of NE area, along the Guadiana, located in the village (Early/Middle and Final Neolithic) of Xarez 12, recently excavated. On a broader scale, the venue of Xarez is part of the big patch of megalithic Reguengos de Monsaraz, with a high concentration of dolmens, isolated menhirs and some great enclosures as well as the remains of a dense network of Neolithic and Chalcolithic settlements.
The monument is located on a very flattened area, with a slight slope facing East generally. The are granite outcrops in the immediate area, although the venue occupies a “clearing” free of outcrops.
The enclosure of Xarez marks, on the other hand, the easternmost extension of the menhir sets in Central Alentejo, is more or less directly related to the occurrence of granitoid rocks.
The site was discovered and restored in the seventies of the twentieth century by J. Pires Gonçalves and was recently dismantled and relocated in the immediate landscape surrounding the Regional Museum of Archaeology in Monsaraz. The original site is now submerged by the waters of the Alqueva dam.
