Roman Rig

They are believed to originally have formed a single Dyke running from near Wincobank in Sheffield to Mexborough.

The southern branch passes through Greasbrough, intersecting the River Don just south of Swinton at Kilnhurst.

The northern branch passes close to another Iron Age fort at Scholes Coppice and runs to the north of Swinton, meeting the River Don at Mexborough.

Part of the western end of the ridge was used in the Middle Ages to demarcate the boundary of Ecclesfield and Sheffield.

This western part parallels the Don, and a report of 1891 in the Sheffield Independent stated that it had formerly run as far west as Bridgehouses.
