The Diocese of Norwich is one of the oldest dioceses in England. Its origins date back to Dunwich (AD630), Elmham (AD673) and Thetford (AD1070). It was founded as the Diocese of Norwich in 1094. It covers 1,804 square miles with a population of approximately 815,000.

The Diocese comprises all Norfolk (the fourth largest county in England) except for a small area in the extreme west, mainly the marshland beyond the Great Ouse which is in the Diocese of Ely. A small area of Suffolk, known as Waveney, is also in the Diocese of Norwich, namely the port of Lowestoft and the associated Deanery of Lothingland. There are 26,410 people on the electoral rolls of the 577 Church of England parishes, with 209 benefices and 648 church buildings.

Diocesan House
The 577 parishes are the primary area of the Church's work in the Diocese and are assisted in their ministry by a number of resource teams which are based at Diocesan House.

Diocesan House is the administrative centre of the Diocese. It is situated in Easton at the west end of Norwich’s southern by-pass, the A47. Diocesan House provides a base for the diocesan resource teams and administration. Visitors are welcome and committee rooms are available for meetings if booked in advance.
