The Antas do Olival da Pêga are located near the village of Telheiro, in the municipality of Reguengos de Monsaraz, in the Évora district of the Alentejo region of Portugal.

They include necklace beads made of quartz and other materials in various shapes, bone figurines of rodents and rabbits, many ceramic fragments of up to 200 vases, with four showing decorations; 134 schist plaques; and a small idol in shale.

[4] It was thus not until the 1990s that excavations were carried out, by Gonçalves and Sousa, which enabled them to date the tomb from the end of the 4th millennium BCE.

Gonçalves and Sousa identified a 16-meter-long corridor, the longest in Portugal, that connected the anta with four other funerary structures made up of three beehive tombs, or tholoi, and a grave.

Many items, dating from around 2900-2500 BCE, were found in one tholos, including bones; flint, chert and rhyolite blades; arrowheads; dart tips; axes; polished stone artifacts; hair pins; necklace beads; ceramics; a copper dagger, and a bone figurine of a fox.
