Monument record MRM 120 - Bronze-Age ring ditch, possibly the remains of a round barrow, visible as a cropmark.

A ring ditch, possibly the remains of a round barrow, is visible on aerial photographs as a cropmark on the former area of Martlesham Heath, centred on circa TM244455, Martlesham parish. Although somewhat indistinct, it is possible to see that the ring ditch is approximately 36 metres in diameter. The ditch may be variable in width but encloses an area up to 25 metres wide. This ring ditch may be the remains of a Bronze Age round barrow, possibly forming a group with MRM 017 circa 180 metres to the north-east, and a slightly larger ring, MRM 121, circa 65 metres ditch to the south. This feature is located on the former Martlesham Heath airfield and has now been built over.
