Almendres Cromlech

The Cromlech of the Almendres is a megalithic complex, located 4.5 road km WSW of the village of Nossa Senhora de Guadalupe, in the civil parish of Nossa Senhora da Tourega e Nossa Senhora de Guadalupe, municipality of Évora, in the Portuguese Alentejo. The largest existing group of structured menhirs in the Iberian Peninsula, this archaeological site consists of several megalithic structures: cromlechs and menhir stones, that belong to the so-called "megalithic universe of Évora", with clear parallels to other cromlechs in Évora District, such as Portela Mogos and the Vale Maria do Meio Cromlech.
