Afterwards, a new fort (Fort II), still in turf and timber, was built directly upon the destruction layer of Fort I to secure the new border line.įort II was modified in about AD 122 to provide support for Hadrian’s Wall and to accommodate a different garrison of 1,000 infantrymen. It was followed by another fort at the beginning of the 2nd century, but it was burnt down, possibly by enemy action. A decade later, about AD 86, this early fort was abandoned, and the garrison moved to a new turf fort on the present site. Dating to the late 70s and classified as a vexillation fortress, it was probably established as part of Julius Agricola’s planned conquest of Scotland. The first fort at Cordbrige lay around 1 km west of the Roman town at Red House, and was discovered during construction of the A69 road in 1974. © Historic England (illustration by Peter Lorrimer) Reconstruction of Corbridge town at its most extensive, in about AD 225 Coria largely developed after AD 160 and continued to thrive until its abandonment in the early years of the 5th century when Roman administration in Britain collapsed. A number of forts, which are now deeply buried beneath the remains, were built during the 1st and 2nd centuries. The site lies to the west of the modern town, on the north bank of the River Tyne in the English county of Northumberland. Coria (also known as Corstopitum) was a fort and town in the Roman province of Britannia immediately south of Hadrian’s Wall, on the east-west road stretching from Corbridge to Carlisle ( Luguvalium) and now known as the “Stanegate”.
