Anta da Vila de Nisa / São Gens 1

Anta/Dolmen - Neolithic e Middle Ages (772)
The Nisa dolmen or São Gens 1 is located at the top of a small spurred hill, next to the ermida of São Gens (CNS 28307), with a good visual domain over the flat lands of Crato and Serra de São Mamede. It is inserted in a cluster composed of the São Gens dolmen 2, 3 and 4 (CNS 2416, CNS 29551, CNS 12463), which present more degraded conditions. This megalithic monument is composed of a polygonal shaped chamber (about 3m in diameter), formed by seven granite orthostates, about 2.5 m tall, a cover slab and a short corridor, facing east, with a separating step. Traces of the earth mamoa are found on the outside. Inside, several osteological remains and some rock artefacts can be identified (amphibolite ax, flint blade, marble spherical idols), as well as bone artefacts (drill bits) and ceramic containers of different chronologies. The architectural characteristics and part of this dolmen's collected artefacts allow to chronologically frame it in the Final Neolithic/Chalcolithic (3500 - 2000 BC), with funerary reusing during the first half of the 2nd millennium BC and during 11th - 13th centuries AD (Late Middle Ages). The medieval burial of a male inside the Saint Gens dolmen 1 may be associated with the monumentality and symbolic role of this structure to the local communities during this period, possibly related to the presence of graves excavated in the surrounding rock.


The entrance in the monument is free. More information is available on the website of the city council of Nisa (Câmara Municipal de Nisa).

    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.
