Clavell Tower, also known as Clavell Folly or the Kimmeridge Tower, is a Grade II listed Tuscan style tower built in 1830. It lies on the Jurassic Coast, on the top of Hen Cliff just east of Kimmeridge Bay in the Isle of Purbeck in Dorset, England. It is now a Landmark Trust property and in 2006-08 was moved 25 metres back from the crumbling cliff edge.
