Overview
The Anta da Aldeia da Mata, also called the Anta do Tapadão, is a megalithic chamber tomb in the Alentejo, Portugal. It stands two kilometres from the settlement of Aldeia da Mata, in the parish of the same name, in the municipality of Crato, Portalegre district. It is a monument more than five thousand years old, with a catalogue dating of 4000 to 3000 BCE based on typology.
It is notable for its size, perhaps the largest of its kind in Portugal, and for its very good state of preservation. It has been classified as a National Monument since 1910.

The chamber is formed by seven large granite orthostats. Their dimensions (height by width) are 2.62 m by 2.20 m, 2.33 m by 1.50 m, 2.38 m by 0.84 m, 2.10 m by 2.80 m, 1.70 m by 1.16 m, 0.45 m by 1.14 m and 2.24 m by 2.45 m. The slab that closes the mouth of the chamber measures 3.06 m by 2.78 m, and the capstone, or table, measures 4.27 m by 3.35 m and is 30 cm thick.
The second orthostat is broken across its middle. The sixth is reduced to less than its lower half, the missing upper part having fallen outside. The entrance faces east and is extended by a corridor ten metres long, flanked by granite blocks. The mouth of the chamber was closed by an enormous block about three metres wide, which remains in place.

Around Évora, in the Alentejo, megalithic tombs are called antas, and some of the largest in Iberia stand in this region. Monuments of this kind in the region are usually collective tombs.
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.
