The Community Assembly of Norwich is located in the cathedral city and district of the county of Norfolk which claims to be the most complete medieval city in the British Isles. It includes cobbled streets such as Elm Hill, Timber Hill and Tombland; ancient buildings such as St Andrew's Hall; half-timbered houses such as Dragon Hall, The Guildhall and Strangers' Hall and many medieval lanes. The winding River Wensum flows through the city centre towards Norwich Castle.

The capital of the Iceni tribe (Dumnonians) was a settlement located near to the village of Caistor St Edmund on the River Tas about 5 mi (8 km) to the south of modern Norwich. After an uprising led by Boudica in about 60 AD, the Caistor area became the Roman capital of East Anglia named Venta Icenorum, literally 'marketplace of the Iceni'. This fell into disuse about 450 AD.
