Almendres, not far from Evora, is one of the finest megalithic sites in Portugal. The megalithic stone circle is the largest on the Iberian peninsula and one of the oldest in the world. The monument is probably more than 7,000 years old, build during the transition from a hunter-gatherer culture to an agricultural culture. It was only discovered in 1966.
The monument consists now of around 100 upright stones. There are signs that it has changed over the centuries (stones have been removed and new ones added). The site is easy to find by following the clear sign-posting from the small village of Nossa Senhora de Guadelupe.
Close to the stone circle stands the menhir of Almendres. This is clearly marked with signboards.
