Megalithic Monuments
History & Heritage
The Algarve possesses a rich but often overlooked prehistoric heritage that includes megalithic tombs, standing stones and settlement sites dating from the Neolithic and Copper Age periods, roughly 5,000 to 7,000 years ago. While less famous than the megaliths of Brittany or the Alentejo, the Algarve's prehistoric monuments provide evidence of sophisticated societies that lived in the region millennia before the Phoenicians, Romans or Moors arrived.
The most significant concentration of megalithic monuments is found around Alcalar near Portimao. The Alcalar necropolis is a complex of over a dozen Neolithic and Copper Age tombs dating from approximately 3000 to 2000 BC. The principal monument, known as Alcalar 7, is a large tholos (beehive) tomb with a stone-lined corridor leading to a domed burial chamber. It is open to visitors as part of an archaeological park with an interpretation centre.
The Alcalar monuments indicate the presence of a complex, hierarchical society in the Algarve during the 3rd millennium BC. The construction of large communal tombs required considerable organisation and shared belief systems. Grave goods found at the site, including polished stone tools, pottery, copper artefacts and items of adornment, suggest social stratification and long-distance trade connections.
Other megalithic sites include the menhirs (standing stones) of the western region. The Menhir of Lavajo, near Alcoutim, stands over 3 metres tall. Menhirs are also found near Loule, Silves and in the Monchique area. Their purpose remains debated, with theories ranging from territorial markers to astronomical alignments.
The Anta (dolmen) de Pedra do Alagar, near Loule, is a chamber tomb formed by large stone slabs. Several other antas survive in the Barrocal and the foothills of the Serra de Monchique.
Rock art sites add another dimension to the Algarve's prehistoric record. Engravings and paintings have been found in rock shelters in the Monchique area and along the Costa Vicentina.
The interpretation of the Algarve's megalithic heritage benefits from comparison with the much more extensive megalithic landscape of the Alentejo. The great stone circles and passage graves of sites such as Almendres and Zambujeiro represent the broader cultural context.
Local museums in Faro, Silves, Portimao and Lagos display artefacts from regional excavations. The Alcalar interpretation centre provides the most accessible introduction to the Algarve's megalithic heritage.
