Conjunto megalítico da Herdade do Xerez, Stone circle at Herdade do Xerez near Monsaraz, Portugal.

The Xerez Cromlech is a square arrangement of 55 granite menhirs around a central phallic stone about 4.5 metres high and weighing 7 tons. The smaller stones, between 0.37 and 2.1 metres tall, vary in shape from ovoid to polyhedral. Seven menhirs, including the central one, carry carved motifs. The square layout was created in 1969–1972 by amateur archaeologist José Pires Gonçalves, not found in situ.

This stone circle dates to the Neolithic period when communities built it as a gathering and ceremonial place. The structure shows that early inhabitants of Iberia created organized social spaces and possessed skills in transporting and arranging large stones.

The square layout is not archaeological evidence but the interpretation of José Pires Gonçalves, a Reguengos de Monsaraz general practitioner and amateur archaeologist who identified the stones as a cromlech in 1969 after two local residents, José Cruz and Leonel Franco, alerted him to the central phallic menhir. He had the stones re-erected around it in 1972.

The site sits in open rural surroundings and is accessible on foot via marked paths from Monsaraz. Visitors should bring sturdy shoes and plenty of water since there is little shade and the ground is uneven.
