NHER 57994 (Monument record) - Vegetation marks of undated ditches

August 2012.
Vegetation marks which possibly relate to underlying ditches are visible on aerial photographs within the northern part of Coltishall airfield (S1). The site is centred on TG 2731 2357. It must be stated that there is a relatively high level of uncertainty over the origin and significance of these vegetation marks. The fact that these features appear to be showing as ditch-like features on grass within a recently active airfield means that further work would be needed to establish if these do relate to actual archaeological features. However vegetation marks with a similar appearance elsewhere in the airfield where found to relate to former medieval to post medieval boundary ditches depicted on historic maps, see NHER 57995 for discussion and it is therefore feasible that these marks also relate to underlying ditch-like features. It is worth noting that these possible ditches follow a broadly similar alignment as the nearby prehistoric enclosure and fields (NHER 36729) and therefore could potentially represent a further element of this site.
