Monument record DUN 044 - World War II military strong point, on which was later built a WWII military camp and possible site of diver battery H3

A military strongpoint can be seen on aerial photographs from 1941 (S1), c 500m north-west of Dunwich. This feature consistes of a stretch of barbed wire partially encircling a possible pillbox and a possible covered trench - possibly an early air raid shelter. By June 1945 (S2), this site has been destoryed by the construction of a military camp on top of it. The camp consists of a number of Nissen-type huts, trackways, small weapons pits, gun emplacements and a stretch of slit trench. The camp can still be seen, in the same form as it was in 1945, on aerial photographs from 1946 (S3).
Possibly also the site of a Second World War heavy anti aircraft (Diver) battery in the Diver Strip at north-east of The Granary.
