Anta 3 da Aldeia de Bertiandos

Anta/Dolmen - Neolithic (2859)
The Anta 3 da Aldeia de Bertiandos is located close to the Barragem de João Maçarico, located a small distance away from Anta 1 (CNS 2857) and 2 (CNS 2858) from the Aldeia de Bertiandos. This megalithic monument was composed by a chamber of polygonal blueprint (with roughly 2.50m in diameter), formed by nine orthostates, one of which was closing the entrance, and a corridor, with four orthostates on the left side and three on the right side (with roughly 1.93m of maximum length). Nowadays, this dolmen is almost completely destroyed, with only a few rock elements which composed the original structure being observable. A vast and diverse artefact collection was found on the inside, composed of lithic-flaked artefacts (six silex geometrics, two quartz arrowheads, a blade fragment, and a silex lamella), five axes and two adzes made of polished stone, two milling stones/ anvils, a spherical vessel and a set of ten disc-shaped shale beads. The architectonic characteristics of this dolmen, combined with the recovered artefacts, allow to chronologically frame it during the Late Neolithic / Chalcolithic.


Monument integrated in the Coruche Megalithic Route, Martinianos Route. Contact the Coruche Museum in advance to complete the tour.

    Good practices when visiting archaeological sites

    To visit an archaeological site is to connect with our origins, to understand our path and evolution as a species integrated in the environment, and to respect and safeguard our heritage so that future generations can also visit and enjoy it.

    Walking the paths and enjoying the structures and archaeological pieces that survived over time, fosters the understanding of what is different, but also of what is common among different populations: basically, what identifies us as Homo Sapiens.

    More than just vestiges and ruins of the past, archaeological sites showcase our capacity for creative thought, adaptation, interconnection, comprehension and resilience. Without these traits we would not have been successful as cultural beings participating in an ongoing evolutionary process. These sites also allow to consider choices made in the past thus contributing for decisions in the present to be made with greater awareness and knowledge.

    Archaeological sites are unique and irreplaceable. These sites are fragile resources vulnerable to changes driven by human development. The information they keep, if destroyed, can never be recovered again.

    As such, the Directorate-General for Cultural Heritage (DGPC) invites all visitors to enjoy the beauty and authenticity of these sites, while helping to preserve them for future generations by adopting the following set of good practices:

    • Respect all signs; 
    • Do not try to access fenced areas; 
    • Do not climb, sit or walk on archaeological structures and remains; 
    • Respect areas where archaeological excavations are being carried out, not disturbing them; 
    • Do not collect materials or sediments;
    • Do not write or make graffiti on archaeological structures; 
    • Put the garbage in appropriate containers. If none exist, take the garbage with you until you find a suitable container; 
    • Leave the archaeological site as you found it; 
    • Do not drive bicycles or motor vehicles over archaeological sites; 
    • Respect and protect the plants and animals that live in the areas surrounding archaeological sites;
    • Report signs of vandalism or destruction to DGPC or Regional Directorates of Culture (DRC);
    • Share the visiting experience and the archaeological sites, as a way of raising awareness to their preservation and making them better known;
    • Do not buy archaeological materials and report to public security authorities, DGPC or DRC, if you suspect that archaeological materials may be for sale.
