Chew Green
Chew Green is the site of the ancient Roman encampment, commonly but erroneously called Ad Fines, in Northumberland, England, north of Rochester and 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 a medieval settlement 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. The largest camp structure is a square that encloses about with a defensive rampart and ditch. Evidence inside the fort indicates it was used as permanent settlement. The encampment likely served only as a military base, not a colonial settlement.
The site is within the Northumberland National Park and within the Military Training Area at Otterburn.
