Alentejan megalithic landscapes
Close to the menhir of Barrocal (the biggest laying menhir of Iberia), we found a huge granitic outcrop with the stigmates of having been the source (quarry) of the menhir.
This fact is, of course, a splendid example to think about the relationship between megaliths and natural rock outcrops in the way Chris Scarre has suggested recently.
This outcrop, apart from a very striking anthropomorfic aspect, shows also, on the façade, a vertical natural shelter, going deep inside the rock, and another vertical gap, crossing all the formation and paralel to the façade.
