Scheduled Monument Report:
The monument includes a cross dyke of prehistoric date cutting off the promontory formed by the confluence of the Dovecrag and Holystone Burns. The dyke is formed by a ditch 4m across and 1.5m deep with the upcast from the ditch thrown to the eastern side to form a rampart 4.5m wide by 1.5m high which runs parallel to the ditch for its entire length of 390m. The dyke runs between the two burns across the central hilly section where it is bisected by a Roman road. North of the road the dyke is less straight and a pronounced twist can be seen. The road and the forestry plantation wall which bisect the cross dyke are excluded from the scheduling, although the ground beneath them is included.
Comments:
Analysis shows that there maybe another Dyke missing from the Scheduled Monument that joins this Dyke with NT91943 08021 (1008274) in the direction of old quarries.
