The work has examined remains of mainly Roman date, although medieval and later structures have also been investigated.
Recent discoveries at Bedale Street may also cast light on the elusive Saxon settlement of Southwark.
A section of the main Roman road to the first London Bridge was uncovered as well as the remains of numerous buildings of Roman date, including a collapsed wall faced in decorated plaster.
The remains of medieval and later buildings were observed to the rear of The Wheatsheaf above numerous Roman structures.
