Description
The ha-ha wall at Duncombe Park, dating from the 18th century, is a curving structure that extends from the northern stable block to the Ionic temple. It is attributed to the landscape designer William Bridgman. The wall is constructed of sandstone and features 4 to 5 rusticated courses topped with capstones. The wall is referenced in Hussey's "Duncombe Park I and II" published in Country Life on December 5 and 12, 1957, and in Pevsner's "Yorkshire: the North Riding" from 1966.
