Archaeologists have unearthed well-preserved remains of early medieval buildings in Winchester, Hampshire.
The dig is thought to be the largest in the UK at the moment
The dig is taking place at Northgate House, in advance of the planned redevelopment of the site.
A series of walls have been discovered in the excavation, the biggest that the city has seen for twenty years.
Artefacts from the Roman era that have also been found include a commemorative coin from 300 AD, a miniature set of scales, and a tool for etching.
Senior archaeologist Phillip Emery said: "It's probably the largest piece of archaeological fieldwork going on in the UK at the present time.
"The significance of the site lies in the tremendous survival of archaeological deposits from all periods, from the late iron age through the Roman, Saxon and medieval eras."
The dig will continue until the middle of January.
