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. You can find out how coastal stacks are formed as a headland erodes here.
