Skomer Island (a Scandinavian word which describes the cloven shape of the island) ranks among the finest archaeological landscapes in Britain. Its comparative isolation from the mainland, and the limited impact of recent agriculture, has meant that considerable tracts of Skomer have not been ploughed or built on since prehistoric times.
It is now famed for its wildlife and ecosystems, but on the unploughed parts of the island small huts, animal pounds, farmsteads and elaborate systems of fields survive from the Bronze and Iron Ages to show us the ways in which our prehistoric ancestors lived and worked the land. A detailed survey by John Evans, published in 1990, together with earlier survey work by W F Grimes represent our main source of information.
