A must visit: it is the jewel among the megalithic funerary monuments in all of Beira Alta! It was classified as a National Monument in 1961, given its rarity and exceptional importance in the context of the national prehistoric heritage.
It is located in the center of a wide plateau and stands out in the landscape for the heritage set in which it is inserted.

It is a large dolmen that was Christianized in the Middle Ages through the construction of a chapel, the burial chamber having been adapted to the religious space. It is a monument formed by a polygonal chamber, with a long corridor and atrium.

The archaeological interventions made it possible to get to know the funerary monument in depth and several finds were exhumed, today exposed in the Espaço Identidade e Memória, such as blades, axes and ceramic containers, microliths, a spheroid and even coals related to ritual bonfires (dated between the years 3290 – 3010 BC)
