To the south of Bosherston village, on the crest of a low summit at 41m above sea level, are the badly-ruined remains of what appears to be a windmill tower. The stone rubble-built tower is circular in plan, roughly 4m in diameter, with parallel sides, and stands about 5m high. The facing stonework has been removed from the lower 2m and about a third of the stone wall has been removed from the north side, leaving the structure in a parlous state. The tower is not shown on any Ordnance Survey mapping despite its size and prominent location.
