Chew Green

Chew Green is the site of the ancient Roman encampment, commonly but erroneously called Ad Fines on the 1885-1900 edition of the Ordnance Survey map, in Northumberland, England, 8 miles north of Rochester and 9 miles west of Alwinton. The encampment was adjacent to Dere Street, a Roman road that stretched south to York, and almost on the present-day border with Scotland.

Archaeological excavation at Chew Green has uncovered a complex of Roman military camps consisting of a Roman fort, two fortlets, two camps and a section of Roman road. The Roman remains were overlaid with evidence of the medieval settlement of Kemylpethe that included a small chapel, although the evidence for this latter is based on reports of an undocumented excavation in the 1880s and must be regarded as insubstantial.
