Anta de Carcavelos

The Anta de Carcavelos, located close to the village of Carcavelos near the town of Lousa in the municipality of Loures in the Lisbon District of Portugal, is a stone age dolmen (burial chamber) or megalithic monument from the Chalcolithic period. It is one of many such tombs that have been identified in Portugal.[1][2]

The Anta was a communal grave consisting of a sepulchral chamber with a polygonal shape. The remains of the tomb consist of six cretaceous limestone slabs that originated in the area, which has several sizeable limestone outcrops. Five of these slabs are believed to have been part of the burial chamber and the sixth part of the corridor. Near the monument there are other slabs of limestone, one of which of could have been the roof of the chamber.[2][3]

Based on earlier identification by Mesquita Figueiredo and Carlos Ribeiro (1813-82), the German archaeologists Georg and Vera Leisner visited the Anta of Carcavelos in 1944 as part of preparing a systematic inventory of the Neolithic tombs of the Lisbon area. They produced drawings but did not carry out any excavations. Hastened as a result of looting at the site, the first excavations were carried out in 1986 and continued again from 1991-94, under the supervision of Gustavo Marques of the Loures municipality. Further intermittent excavation was carried out in 1998 and again in 2005-06 by Florbela Estêvão and Rui Boaventura.[3]

From the studies carried out in 1994, many bones were collected, with over 80 adult males and females believed to have been buried there. Various objects were also found such as flint arrowheads, smooth and decorated bell-shaped ceramics, dishes, cylindrical idols, and objects of adornment. The items collected came mainly from the interior of the chamber, but some were also found close to the site. In general, the number of items found was significantly lower than those found at other comparable sites in the area, such as the Anta do Monte Abraão. The evaluation of items found suggested a probable initial use of the dolmen as being in the last centuries of the 4th millennium BCE, with an intensification in its use between 3000 and 2600 BCE, this period having been identified using radiocarbon dating on an adult femur and jaw.[1][3]

Preliminary microscopic analysis of human bones indicates cut marks. This suggests that the bodies could have been disarticulated and/or defleshed prior to burial in the dolmen, which thus served as an ossuary rather than as a repository of bodies. However, archaeologists recognise that further work is required to confirm this.[1]
