More information : The earthwork and cropmark remains of the Turf wall and its ditch were seen in fragmented sections between NY 6000 6565 and NY 6183 6636. This was mapped from historical aerial photographs as part of the English Heritage: Hadrian¿s Wall NMP project. (1-6)
A length of the turf wall section of Hadrian's Wall and associated wall ditch and glacis are visible as extensive earthworks on air photographs and digital elevation models derived from Environment Agency lidar and Structure from Motion taken from 2017 specialist oblique photography, stretching from NY 6003 6566 to Birdoswald Roman fort at NY 6116 6620.
Most of the turf wall itself has largely been ploughed level, though there is a 240 metre stretch of good survival between NY 6034 6571 and NY 6057 6576. The wall ditch and northern glacis are well defined along most of this section. East of Milecastle 50 (14014) the earthworks become increasingly denuded.
Immediately west of Birdoswald fort (13993), at NY 6136 6621, there are only the slightest of traces of linear banks and ditches, which align with the better surviving examples of the turf wall, ditch and glacis and are therefore considered to be a continuation of the same. Interestingly, these linears only partly correspond with the alignments of vicus buildings discovered through geophysical survey here which, along with the fort, superceded the turf wall.
