Old Harry Rocks at Handfast Point are a small but characteristic set of coastal landforms off Ballard Down at the eastern end of the Jurassic Coastworld heritage site near Swanage in Dorset. The rocks include a collection of islands, a natural arch, stacks and stumps on a wave cut platform formed by erosion of the chalk cliffs. The rocks are part of a once continuous band of chalk which ran through south Dorset, Ballard Down and the Isle of Wight, part of the southern England Chalk Formation.
