Scope and Content Roof ventilator, World War II engine room, Hoxa Battery, Hoxa Head, South Ronaldsay, Orkney Islands In both World Wars coast batteries were built to protect the channels into Scapa Flow and Kirkwall Bay, where there was an important contraband control. The greatest concentrations of firepower were at the main north-western and southern entrances to the Flow, the latter covered by the coast batteries on Stanger Head on Flotta and here on Hoxa Head on South Ronaldsay. This detail shows a dormer-style ventilator set in the concrete arched roof of the engine room, a feature designed to assist in the dispersal of the diesel fumes within the building. The joints in the face of the concrete roof, visible in this view, reflect the way in which the concrete has been erected in 'lifts' against shutter boards used in its construction. 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.
