The anta consists of seven orthostats (esteios), a slab and a small corridor formed by two orthostats lying flat and oriented to the east. The monument has been restored, and some orthostats that had fallen were set upright again. Traces of a mound (mamoa) have been identified, showing that the anta was partly buried; this structure has also been partly restored.
The slab, or capstone, measures two metres by three and a half metres.

The capstone bears some pecked cup marks (covinhas). Identical cup marks, as well as some engravings, were found on rocks near the dolmen. Some of the orthostats carry engraved cup marks and grooves. On one orthostat, the third counting from the left side of the polygonal chamber, there are traces of red painted decoration.

Tradition and region
About this kind of monument
Portuguese antas of the Alentejo
Around Évora, in the Alentejo, megalithic tombs are called antas, and some of the largest in Iberia stand here. The Great Dolmen of Zambujeiro, near Valverde in the municipality of Évora, is considered one of the biggest such structures in Iberia. Research has dated it to between 4000 and 3000 BCE, concurrent with the megalithic building of the Évora region, and it is linked to the Great Dolmen of Comenda da Igreja at Montemor-o-Novo. Henrique Leonor Pina excavated it in 1965, and although his methods caused some controversy, the work recovered slate tablets, necklaces, crosiers, copper objects, ceramics and carinated bowls. The Portuguese government declared it a national monument in 1971.
The finds show that the tombs were used for generations: slate tablets, personal ornaments and copper objects in the chambers reach into the Chalcolithic, so one anta can carry evidence for several centuries of burial custom. Excavated anta chambers are the main source for dating, since the stones themselves cannot be dated.
Nearby, the Almendres Cromlech is a large group of standing stones, a reminder that the Alentejo's megalithic landscape also includes open-air stone enclosures and single menhirs, not only tombs.
The Atlas's records here include small antas, some reduced to a few standing slabs, and many lack a secure excavation date. They are labelled with a typological range.
When visiting, look for the chamber and the passage that leads to it, and for the way the monument sits in its field. Check access in advance.
