Anta 1 da Herdade da Água Doce/ Anta de Vale Beiró

Anta/Dolmen - Neolithic e Chalcolithic (Copper Age) (17170)
The Anta 1 from Herdade da Água Doce or Anta de Vale Beiró is located in a small elevation, roughly 200m south of Monte da Água Doce, east from the Vale Beiró stream, close to the Anta 2 from Herdade da Água Doce/Anta Grande do Caminho da Fanica (CNS 17171) and from the Anta 3 from Herdade de Água Doce/ Anta Pequena do Caminho da Fanica (CNS 17172). This megalithic monument is composed by a polygonal shaped chamber, measuring 2.5m in diameter and 2.7m tall, formed by seven orthostats and (five of which preserved in situ) and a large cover slab. Facing east, the corridor was composed of five orthostats on the left side and six on the right side (measuring roughly 2.37m long), which is found in a poor state of preservation. Traces of the mamoa can be found on the outside, which might have been covered by granite and milky quartz with the purpose of being noticeable in the landscape. A vast and diversified set of artefacts was found inside the monument, composed by lithic flaked artefacts (two silex trapeziums ), six silex blades, two rock-crystal quartz lamellae and about 77 silex, shale and rock-crystal quartz arrowheads), four quartzite percussors, 22 polished stone axes and adzes, 15 complete ceramic vessels, six stoneware plaques, one of which of anthropomorphic shape, 11 engraved shale plaques, 22 disc-shaped beads and two pendants. The architectonic characteristics of this dolmen, combined with the recovered artefacts, allow to chronologically frame it during the Late Neolithic/Chalcolithic (3500 - 2000 BC).

    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.
