The following Gun Defended Areas had permanent HAA sites. The maps on each page show the approximate location of these sites based on modern maps. Also given is the following information, where known: Site name, site code, modern OS 6 figure grid reference.
Additional information may also be given such as armament, dates active and units deployed. Note that not all sites shown may have been occupied at the same time.
Only those sites that are part of the GDA are shown. Sites from neighbouring GDA’s and temporary “Diver” sites are not shown.
Additional locations are also shown such as Light Anti-Aircraft sites, Coastal Batteries, Radar Stations and War related sites (Ordnance Factories etc.).
Anyone thinking of exploring any of these sites should be aware that a lot of them now lie on private land. Permission should always be sought before visiting these sites. Very little remains visible at most sites and many have now been built over.
