West of the village of Dafni in north central Evia, ruins of a castle can be seen on a low hill at Kastro, near the road heading to Strofilias. The structure dates back to the 5th century BC, though a large number of artefacts including statues and pottery as well as graves have been found in the area and suggest that it was inhabited from the Geometric era.
