A Brief History
Built in 1942 the Dome is a Scheduled Ancient Monument and is now owned by the North Norfolk Historic Buildings Trust. Situated on the edge of Langham's RAF base, one of the wartime uses of the Dome was as a trainer for anti-aircraft gunners in ground to air defence. Rendered externally with concrete, which has a metal rod and mesh sub-structure, the interior of the Dome was lined with white fibreboard and had moving images of targets projected on to it. 
Trainees, using replica weaponry equipped with a light beam, would aim at the targets to improve their accuracy and level of success. It is the intention of the Trust, together with the Friends of Langham Dome, to repair and restore this building and incorporate an interpretation of its training facilities.
In the war, the Dome used ground breaking technology, as this 1941 top secret document reveals. Technicolour Limited, the producers of the 'Cinematographic Apparatus' used in the Dome, outline the features they want to patent....
The Langham Dome sits on the edge of the former Langham RAF base where during the 1939-45 war service men and women from the United Kingdom, Australia and New Zealand were stationed.
