If you want to discover more about the history and purpose of this megalithic complex, keep reading! You’ll also learn how to get there and what other archeological sites Evora is home to.

Almendres Cromlech – History

Archeological discoveries in Portugal aren’t uncommon. After all, the region had human settlements as early as 400,000 years ago! This is confirmed by the oldest human fossil found in the country. It was a skull that had been deposited 400,000 years ago in the Cave of Aroeira in Santarem. Another fossil that sheds light on the human population of the Iberian Peninsula is a tooth found in Nova da Columbeira cave in Central Portugal.

Almendres Cromlech is located in the Alentejo region. During the early Neolithic era (1,000–4,500 BCE), when Almendres was built, this territory was probably inhabited by Mesolithic populations.

Like its English counterpart, Stonehenge, Almendres was built in several stages:

  1. 6th-5th millennium BCE – the construction of the triple-ringed stone circle; the largest ring had a diameter of 18.8 meters (61.7 feet), while the smallest had a diameter of 11.4 meters (34.7 feet). 
  2. 5th-4th millennium BCE – the construction of a double-ringed ellipse built on the west side of the circle that had been built a millennium earlier; the largest ellipse was 43.6 meters (143 feet) at its widest side.
  3. 4th-3rd millennium BCE – alterations made to the original constructions, such as the carving of symbols on stones.

This archeological site was discovered only in the 20th century by Enrique Leonor Pinas. He was carrying out geological fieldwork when he stumbled upon this long-standing treasure. Excavation work was carried out for over four decades. At first, they were done under the supervision of Pinas. In the 1980s, the excavation was carried out by M. V. Gomes.

The discoveries were subsequently classified into Almendres I (built during the Early Neolithic), Almendres II (built during the Middle Neolithic), and Almendres III (built during the Late Neolithic) based on the details and periods mentioned above.

Almendres Cromlech – Appearance and Purpose

The Almendres Cromlech site has approximately 95 granite monoliths built in small clusters. Some are 2.5 meters (8.2 feet) tall, others are very small. The whole archeological site covers an area of approximately 70 by 40 meters (230 by 131 feet).

Among the engravings one can notice on the stones are crosiers (some of which are considered symbols of social prestige), zigzag patterns, crescents, phalli, cupmarks, lunar crescents, and curved figures. 

If we use our imagination, we can outline various shapes these stones form. Phillip C. Lucas, for example, from Stetson University, states that the stones look like a round head on the trunk of a body if seen from the top. If seen as an ellipse, one could assume that the structures resemble a planet orbiting a central point.

The site likely served for various purposes over the years:

  • It may have been used for socio-religious rituals.
  • It may have been the place where tribes gathered together on important days.
  • It may have been used for astronomical observations. This has been suggested by the archaeo-astronomer Pedro Alvim, who noticed that the archeological site’s orientation is toward the two annual equinoxes. 
  • It is often argued that the population that had built the site formed a lunar/goddess or solar/god religious group.
  • Particular archeological details suggest a link with fertility deities.

Portugal’s Stonehenge – Location

Almendres, often called Portugal’s Stonehenge, is located in the Evora district on the Herdade do Almendres estate. It is approximately 12 km (7.5 miles) away from the city of Evora. More precisely, you can get there by driving on the national roadway stretching from Evora to Montemor-o-Novo.

During the latest stage of the excavations, the archeologists oversaw the construction of the pedestrian trail that is now part of the municipality’s megalithic route. The trail takes visitors to other archeological treasures besides Almendres.

Anta Grande do Zambujeiro

Anta Grande do Zambujeiro, which translates as “Great Dolmen of Zambujeiro,” is located in Nossa Senhora da Tourega, Evora. It is a collective funerary monument (dolmens were once used to bury the dead), and one of the biggest sites of this kind in the Iberian peninsula.

The Anta Grande do Zambujeiro structures were likely built less than 6000 years ago. They were discovered during the excavations carried out by Pinas, who also discovered Almendres Cromlech. At the same site, specialists recovered prehistoric necklaces, crosiers, ceramics, and copper objects.
