The dolmen has a polygonal chamber measuring 3.30m × 3.10m, with a height of 2.55 metres, formed by nine orthostats and covered by the original capstone, which weighs 7.8 tons. The covered entrance passage is four metres long, one metre wide and 1.40 metres high. It has four monoliths on each side, two of them on the north side being original, and is covered by four other monoliths, none of which is original.
The tumulus that would have covered the dolmen is no longer visible, although vestiges of the stones that marked its exterior can be seen. It had a diameter of between 13 and 15 metres.

The site lies in a valley at an altitude of 502 metres, on the banks of the Sezures and Oronho streams. Granite outcrops were once abundant in the area but have now been largely destroyed by mining. The dolmen is surrounded by a forest of maritime pine.

The monument was first mentioned in 1911 in the newspaper O Século and was later documented by the ethnographer and archaeologist José Leite de Vasconcelos. The first excavation, in 1911, was carried out by José António Domingos dos Santos, who found 12 mushroom-shaped flint and quartz points, 10 flint points, 2 rock crystal points, a polished stone axe, fragments of clay vessels, bones and charcoal.
Further excavations from 1998 uncovered a total of 1,075 additional objects. These included 84 mushroom-shaped points of flint and milky quartz, 19 microliths, 12 blades, 15 bladelets, two scrapers, four hand mills, a polished axe, a triangular pendant, various types of bead, spherical ceramic vessels, eight truncated conical carinated vessels and five bell-shaped beakers. The work was commissioned by the Penalva do Castelo municipality to excavate, restore and enhance the dolmen.

In 1956 Georg and Vera Leisner visited the dolmen and began its classification, but it was classified as a Property of Public Interest only in June 1992. By 1997 its condition was very poor: only three granite slabs remained in their original position, and the capstone lay flat over the orthostats.
Almost the entire monument was reconstructed in the works that began in 1998, since all the monoliths on the south side had been knocked down and only two of those on the north side remained, also lying on their sides. Rocks found nearby were used to replace the missing ones. The dolmen is included in the Megalithic Route of the Viseu Dão Lafões and Sever do Vouga region and can be reached by road.
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.
