Walton Castle is a 17th-century fort located on Castle Hill that overlooks the Walton St Mary area at the northern end of Clevedon, built some time between 1615 and 1620. It was designed as a hunting lodge for Lord Poulett, a Somerset MP. The English Civil War saw the decline of Poulett's fortunes, and by 1791 the castle was derelict and being used as a dairy by a local farmer. In 1978, the castle was purchased for £1 by Martin Sessions-Hodge, who restored the building to its former glory.
