The Anta da Vidigueira is a megalithic dolmen or burial chamber located southwest of the village of Freixo, in Redondo municipality in the Évora district of the Alentejo region of Portugal.

It consists of a polygonal chamber of seven granite pillars of about 2.2 meters in height, with a slightly damaged capstone that has several engraved “dimples”.

However, while the Leisners made an essential contribution to the knowledge of megalithism in the municipality, they carried out no excavations at any of their monuments, probably because their attention was focused on other regions with better local logistical support.

No formal excavations took place until March 2008 when 12 days of fieldwork was carried out by Rui Mataloto of the Redondo Municipality, with the assistance of archaeological students.

Some shale necklace beads were discovered but the polished stone utensils usually found at megaliths in the Alentejo region were missing.
