Scope and Content Air raid shelter, World War II signal station, Stanger Head, Flotta, Orkney Islands In World War II military activities in and around Scapa Flow generated a complex communications network of wireless, cabled and manual signals equipment associated with all three armed services. These ranged from traditional methods of intelligence-gathering, monitoring and signalling, as practised in World War I, to the sophisticated systems of detection and communication which developments in radio and radar offered. The Royal Navy possessed its own radar network (known as AES, Admiralty Experimental Stations) with at least one station in Orkney, on Ward Hill in South Ronaldsay, but its land-based communications operated mainly through a local group of Port War Signal Stations at Stromness (Ness Battery), Kirkwall (Rerwick Head), Lyness and here at Stanger Head on Flotta, where this range of brick buildings, grouped around a four-storeyed tower, replaced a World War I signal station which had stood on the western side of the island, centred upon an equally lofty but timber-built tower designed in the manner of a ship's superstructure, complete with bridge. This long, earth-covered structure is a wartime air-raid shelter which stands close the Stanger Head signal station. It is a surface shelter of a type which has entrances at each end, the entrance at the nearer end being faced and protected by a free-standing, rubble-built blast wall. A kerb of concrete slabs defines the earth-covered mound. At the heart of the Orkney archipelago, Scapa Flow was the main fleet anchorage for the Royal Navy during both World Wars. Its vital importance led to the creation of one of the most concentrated defence networks in Britain. Source: RCAHMS contribution to SCRAN.
