Bowood is the ancestral estate of the 9th Marquess of Lansdowne, Earl Shelburne.
The house and selective areas of parkland are open to the public.

Lord Lansdowne has exercised his rights and a lot of the “historic features” around Bowood have been deleted from the modern O.S. maps. Some references by Grinsell, in The Victoria history of Wiltshire: volume 1, part 1, have been made, but any site visits by O.S. seem to have been made in 1960’s.
