A hall was built on the summit of Hango Hill by the earls of Derby in the years following the execution of William Christian in 1663. The hall was about 10m in length, but now only about a third survives following the erosion of the coastline.


Early drawings show a building with battlements, and it has been referred to as a 'blockhouse'; it seems however only ever to have served as a banqueting hall and a summerhouse, and it was associated with horseracing organised by the Earls along the dunes to the east onto Langness - the first 'Derby' races.
