Perhaps the most famous (and fascinating) type of human relic from prehistoric times are megalithic constructions. These are symbolic or practical constructions made from enormous stone slabs. (Megalith means “large stones”) Portugal has hundreds, if not thousands, of megalithic sites. These generally include funerary structures, standing stones, and stone circles or enclosures.
Use the map in the sidebar to browse or search among the various prehistoric sites. (The “Filters” control in the top right corner allows you to select types of sites.) Highlighted map markers indicate sites that are described on this website. Below is a list of all the megalithic sites on our website (so far!).

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…
