Monumento megalítico do Lousal/Lousal 1

Anta/Dolmen - Chalcolithic (Copper Age) (3964)
The Lousal megalithic monument is located in a flat area, in the eastern front of the Serra de Grândola, about 1500m away from the Lousal Mining Park, near grauvaque outcrops. This funeral monument is located in isolated position, near the Lousal 2 (CNS 7756); Lousal 3 (CNS 7757), Lousal 4 (CNS 11356) and Lousal 5 (CNS 33722) monuments. This megalithic monument, with atypical architecture and difficult characterization, is composed by a circular shaped chamber (about 2.30m in diameter), formed by eight grauvaque orthostates, with about 1.6m of maximum height, a secondary oval shaped chamber or small niche, separated by a narrow passage and long rectangular corridor (about 2.20m long), facing southeast. These characteristics resemble the false dome monuments (tholos). The covering slab, as well as traces of the tumuls can be found on the outside. A diverse artefacts collection was recovered inside this funeral monument, consisting of ceramic vessels (smooth, carinated cups and a high carinated vase), a shale wrist-guard, a Palmela type copper arrowhead, copper puncture, moving part of a quern and ochre nodules. The architectural features of this monument and the materials collected inside it allow to chronologically frame them between the Late Neolithic and the Late Chalcolithic (3500 - 2500 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.
