Old Marble Quarries, currently deactivated. At one time, due to the excellent natural acoustics, a Music Festival called "Pedreira dos Sons" was organized here.
This area was populated in prehistoric times, and there are numerous remains of megalithic settlements. You can freely walk along the signposted trails and see dolmens, tombs, and the so-called "Megalithic Settlement of Herdade das Murteiras."
