Old Harry Rocks are three chalk formations, including a stack and a stump, located at Handfast Point, on the Isle of Purbeck in Dorset, southern England. They mark the most easterly point of the Jurassic Coast, a UNESCO World Heritage Site.
Old Harry and his wife are chalk stacks and stumps respectively and were at one time part of a chalk seam that stretched from Purbeck to the Isle of Wight which included the Needles. With the rise of water after the last Ice Age the sea took its toll on the chalk cliffs.
