Archaeologists hope to find signs of an old Viking town during excavations in Norfolk.

The dig at the Anchor Hotel in Bridge Street, Thetford, is being carried out ahead of a possible redevelopment of the area.

The proximity of the Little Ouse river means there is every likelihood of well preserved remains under the car park, Breckland District Council said.

It is expected the work will take up to six weeks, depending on what is found.
