Old Harry Rocks
See more Jurrasic Coast here.
Old Harry Rocks include a collection of islands, a natural arch, stacks and stumps on a wave cut platform formed by erosion of the chalk cliffs. Sometimes the name Old Harry is used to refer to the sea arch part and Old Harry's Wife to the stump. 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.
