Anta de Agualva/ Anta do Carrascal

Anta/Dolmen - Neolithic (4295)
The Anta da Agualva, also known as Anta do Carrascal, is located in a small elevation (158m in altitude), close to the northern banks of Ribeira das Jardas , in the Agualva village. This dolmen is close from the megalithic monuments of Pego Longo (CNS 3518)m Agualva tholos (CNS 654) and the Antas de Belas set (Pedra dos Mouros - CNS 11301; Monte Abraão - CNS 655 e Estria - CNS 3001). This megalithic monument, facing southeast (conditioned by the characteristics found in the geological outcrop), presents a polygonal chamber, composed by seven limestone orthostates, six of which preserved in situ, and a corridor with only two of its orthostates preserved. Both the chamber and the corridor present a lowered floor level. The artefact collection recovered in this dolmen is reduced, being mainly composed of severely fragmented human osteological remains, silex lithic-flaked artefacts (small blades, two geometrics and a thick blade fragment), an stone wrist-guard and small fragments of ceramic vessels, which have not been relocated in the Museu Geológico. The architectonic characteristics of this dolmen, combined with the recovered artefacts and absolute dating allow to frame its construction and first used during the mid/late 4th millennium BC (Mid and Late Neolithic), being reoccupied during the late 3rd millennium /early 2nd millennium BC.


Free access monument, integrated in the Route of Historical-Cultural Heritage: Sintra Romântica.

    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.
