Prehistoric feature on the island of Shapinsay, Scotland
Castle Bloody is a prehistoric feature on the island of Shapinsay, Orkney, Scotland. Hogan observes that while the feature is marked as a chambered mound[1] on the UK Ordnance Survey map, the structure is more properly and specifically classified as a souterrain or earth house.[2] Slightly to the north is located the ruined historic Linton Chapel.
