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 full article, “Portuguese antas of the Alentejo”, follows below under About this kind of monument.

The Atlas shows 4000 BCE to 3000 BCE for this site, but that is a regional estimate for this kind of monument, not a date for this particular dolmen. No excavation, radiocarbon sample or other measurement is recorded for it, so the real age could fall anywhere within the range, or outside it.
The range rests on this regional background (source: the Wikipedia article “Dolmen”): Most dolmens date from the Late Neolithic period (4000-3000 BCE); megalithic tombs at Algarve in Portugal date to c. 2500 BC.

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.
