Monument record MRM 110 - Possible World War II Light Anti-aircraft gun post.

A possible Light Anti-aircraft machine gun post of Second World War date can be seen cut into an earthwork, possibly a Round Barrow of Bronze Age date, centred on circa TM249446 on Brightwell Heath, Brightwell parish. The earthwork is circa 17 metres in diameter and is still visible on aerial photographs of 1989, although in an eroded and plough damaged form. It is possible the earthwork was constructed specifically to house the gunpost but numerous archaeological features do appear to have been used in this manner (for example see BGL 008). Such defences were built within the perimeter of Martlesham Heath airbase to provide protection against potential invading forces. Defensive features that were constructed within possible archaeological monuments have been transcribed. However, the extensive barbed wire obstructions, numerous slit trenches, pillboxes and related anti-invasion defences which extend throughout the airfield and surround such features have not.
