Monument record DUN 076 - World War II anti-aircraft battery, comman post and diver battery.

A small feature can be seen on 1941 aerial photographs (S1) at TM47766806, to the east of Dunwich Heath on the edge of Minsmere Cliffs. It is a small raised feature or structure with a small trench extending from it. This structure may be a World War II pillbox. To the north-west of this feature on 1945 aerial photographs (S2), a number of irregular circular features can be seen close to the cliff edge. There are 8 such features, and it is likely that these formed one or maybe two anti-aircraft batteries. There are 2 structures nearby, at TM47676808 & TM47696808, which may be the command posts. Some short sections of trackway connect some of these features. The anti-aircraft batteries are likely to be DIVER batteries - a sting of which were constructed along England's east coast during the closing stages of World War II.
