Located in a small cove on the beach that gives them their name, the Fornelos rock engravings are prehistoric inscriptions – dating from approximately the 10th to 8th centuries BC – carved into the limestone of this beach. They represent semi-schematic figures of dimples and ‘horseshoes’, but also deer and horses, animals that were important in the imagination of ancient hunter-fishers. The technique used combines chipping and abrasion of the rock. This site was classified as a Property of Public Interest in 1992, as it is a rare example of rock art in a coastal environment. Although the maritime climate has eroded part of the reliefs, the engravings at Fornelos are still impressive for the precision of their lines and their strong historical value.
