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.
Use the map at the right to search among the various megalithic sites (highlighted map markers indicate megaliths that are described on this website), or browse through the entries below. More posts are added as sites get visited.

Cromeleque das Fontainhas
Also known as: Cromeleque do Monte das Fontainhas Velhas Standing above the flat sandy soil, the stones aim for the sky, pointing the way to heaven.
