Praia das Maçãs Prehistoric Monument

The Praia das Maçãs Prehistoric Monument, also known as the Tholos of Outeiro das Mós, consists of an artificial Neolithic cave and a Chalcolithic domed or beehive tomb. It is situated close to the Praia das Maçãs beach, near the town of Colares in Sintra municipality, in the Lisbon District of Portugal. The area was discovered in 1927. As an important prehistoric sepulchral site, it was classified as a national monument in 1974. Surrounded by housing, the location has been designated as a special zone of protection, and construction is forbidden. Plans by Sintra and the Directorate-General for Cultural Heritage to turn the complex into a museum area, first discussed in 2001, have not yet been implemented. For purposes of protection the site has been covered by sand and there is little presently visible.
