Norwich

Norwich is known to have been a wealthy town and trading centre during the Viking period. It grew rapidly as a centre of trade and manufacture during the 10th and early 11th century. This was due to its location on either side of the River Wensum at its lowest crossing point and just above its confluence with the River Yare.

Around 900 the area north of the river was defended by a large bank and ditch. However by 1066 there is no evidence that the town was still defended.

By the time of the Domesday book Norwich had a population of approximately 5,000 and was the largest centre of population in Norfolk as well as the fourth most populous town in England. Over 1320 burgesses (freeholders of the town) are listed in the Domesday book for 1066. However it was rivalled by Thetford in size and importance.
