The main human relics from prehistoric times are megalithic constructions. (Megalith means “large stones”)
Portugal has hundreds, if not thousands, of megalithic sites. These are broken down into the following categories:
- Tombs
- Standing Stones
- Alignments or circles
Many of these sites are visitable, but some are on private land. As archaeologists excavate these sites, any artefacts of human creation are kept in museums or universities.

Anta da Masmorra
High on a hill, surrounded by nothing but low scrub and forest, stands an abandoned and ruined site: a shattered windmill tower beside the road, forlorn. Just beyond lies the far more ancient Anta da Masmorra, showing less damage than the (relatively) modern windmill. This prehistoric tomb rests quietly in relative anonymity and isolation. It…

Anta das Pedras Altas
Sit on the hill and take in the vista of the Algarve countryside all around you. No town is near enough to hear. You might hear the birds, or possibly barking dogs, but mostly you’ll hear the wind. The dolmen enjoys this peace and quiet, and has done for thousands of years. The noise and…

Anta das Pedras Grandes
The ancient stones stand regally in the centre of a large urban park. Despite the loss of many stones, the anta seems proud to be enshrined in such a prominent spot in the community. Passing dog-walkers may pay no heed, resting or picnicking families may not take time to read the informative plaque, but the…

Anta-Capela de São Dinis
Also called: Anta de Pavia The enormous dolmen stands proudly in the square, grey and hulking beside the traditional yellow and white Alentejana buildings. It presents its original rear towards the square, but as you head around to its entrance its transformation becomes clear. The squared-off stone entranceway replaces the original corridor, and the cross…

Dólmen or Anta-Capela of St. Mary Magdalene
Sitting in the quiet & peaceful church, you can contemplate faith and history at the same time. The church itself dates back to the 16th century, and the hundreds of years of devotion has permeated the azulejo tiles, marble altar, and beautiful stained-glass windows devoted to its patron saint. Then you turn and enter the…

Menir dos Almendres
As you follow the well-trodden (and well-worn!) path, with wired fences on either side of you, you get the feeling that you are simply being herded to something very pedestrian and unimpressive. The nearby farm buildings do nothing to allay you of your suspicions that you are wasting your time. And then the fences fall…

Cromeleque dos Almendres
Stand on the grassy hillside, facing west, surrounded by cork oak trees, and notice the wind blowing and the birds calling. In the far distance, you can just hear the hum of cars & possibly the noise of farmers calling out to their workers. In the far distance, you can glimpse the city of Évora.…

Tomb of Santa Rita
The Algarve is known for its sunshine and beautiful beaches, but if you’re faced with a foggy Atlantic morning, it’s a perfect opportunity to pay a visit to the Megalithic Tomb of Santa Rita. The eerie silence, trees looming out of the fog, the sense of isolation …all lend themselves perfectly to the exploration of…

Barreira Megalithic Complex
Portuguese name: Conjunto Megalítico de Barreira, or Menires de Barreira Standing on the hilltop, surrounded by tall trees and lush undergrowth, you are surrounded by a tumbled abundance of giant stones, some standing brightly in the sunshine, with others covered in moss and/or ivy. To the east, you can see the Sintra hills, topped with…

Menir de Aspradantes
Standing on a ridge of a hill, looking over the fields in the western Algarve, the silence belies the hum of traffic on the distant motorway and the whirr of the towering wind turbines on the far hills. These monumental emblems of the modern age of electricity seem to mock the tiny stone standing alone…
