The Wall remains are situated near St George's Minster, right in the heart of modern Doncaster.
Part of the Roman Fort was established around 70–79 AD under the Emperor Vespasian to guard a vital crossing over the River Don and control movement along Ermine Street.
It is suggested that Doncaster was chosen as the site for a Roman auxiliary fort because it lay on the border between the powerful and truculent Brigantes tribe north of the river, and the relatively civilised and peaceful Coritani, which southern tribe had been quickly incorporated within the Roman provincial system.
The original timber fort was demolished in the 2nd century AD and later replaced by a smaller enclosure protected by a substantial limestone and clay wall roughly 2 meters thick.
The remaining archaeological deposits and wall footings are designated as a scheduled monument protected by law.
An information board shows the layout of the fort.
