This is the position of the stretch of Hadrian's Wall between Harlow Hill to the east and Whittle Dean Watercourse to the west. Nothing can be seen of the Wall, which is beneath the modern B6318 road. The wall ditch, to the north of the Wall, is not visible for most of this section, although it can be seen 200 metres west of Harlow Hill as an earthwork. The exact locations of turrets 16a and 16b have not been identified, although they lie buried somewhere under the modern B6318 road. All the structures described here are Scheduled Monuments and are protected by law. They form part of the Hadrian's Wall World Heritage Site.
