|English: Oxford: Roman Road in Blackbird Leys This unprepossessing little back lane is in fact the route of a 16 mile long Roman road that was, and still is, used to define the eastern boundary of the parish of Sandford-on-Thames. The route here crosses Northfield Brook. (Photo credit: Wikipedia)|
Archaeologist Jane Harrison, who is leading the project, said the group had already found the remains of old walls, pottery and floor tiles.
She said it was not just the city centre which boasts a wealth of history.
"One of the things that's really become clear is that that early Medieval period... was also a really important time in east Oxford and there were a lot of exciting things going on," she said.
The archaeology and history of east Oxford is thought to include Roman settlements, a medieval leper hospital and Civil War siege works.
The dig is part of a collaboration between volunteers and the University of Oxford.
