Monument record NBN 033 - Medieval or Post Medieval field system, visible as cropmarks.

A field system of probable medieval or post-medieval date is visible on aerial photographs as cropmarks to the north east of Newbourne village. The cropmark boundaries are on a north-east to south-west alignment, one of which largely matches the location of a boundary marked on the First Edition Ordnance Survey map of circa 1884, although with some minor differences which suggests it may be of earlier date; the cropmark appears to curve around the northern edge of ring ditch NBN 009, whereas the mapped boundary doglegs to the south. This may support an interpretation that the cropmark boundary was created to avoid the ring ditch when it was a substantial ditched and banked upstanding monument and the mapped boundary was adapted later to avoid only the remains of an inner mound.
