Thornhill is a village in the county of Cumbria, England, south of Whitehaven and north of Seascale, close to St. Bees, and only a few miles from the Irish Sea. The village was created by Whitehaven Rural District Council and Egremont Urban District Council in the 1920s, as part of the national campaign to improve housing conditions, keeping a promise made by the Government to soldiers fighting the First World War.
