Norwich is the major City of Norfolk and of East Anglia. It is situated along the lower banks of the river Wensum lying in a valley where the Norwich Crag forms gravel terraces along the river banks. It is probably the lowest crossing point on the Yare/ Wensum river system, the river itself being both tidal and navigable. Although Roman roads ran through the present city there is little evidence for intensive occupation before the ninth century. The earliest settlement seems to have occurred in the area north of Fye Bridge, where gravel is on both sides of the river.
A handful of our churches may have been founded in this period, but almost certainly all were timber built.
Subsequently, Norwich seems to have rapidly developed in the tenth century, influenced by Scandinavian settlements. Place name evidence, and some objects confirm an Anglo-Scandinavian culture. Some of the early church dedications also belong to this period.
By the eleventh century Norwich was a large borough, with defensive ditches.
Thus although the exact foundation dates of the various churches are unknown, we can be confident in saying that most of them were founded by the end of the century . We do know that the three churches of Mancroft Ward - St Giles-on-the-Hill, St Peter Mancroft, and St Stephen - were founded to serve the French borough, itself; and it is notable that in comparison with others, their parishes are very large. The two St Georges (Colegate and Tombland) were probably of later foundations, as it was not a popular dedication until after the first Crusade (1096), and both of them are intruded into the street plan, and cause it to bend out of alignment.

Alternatively a church could have been seen as a financial investment, conveying rights and a share of the tithe income. It is possible that churches were also used for commercial uses as well as religious. There may indeed be a whole range of reasons. We are unlikely to ever know.
By the 12th Century church reforms had brought parish churches under control of the Church, and measures had been introduced to stop the proliferation of churches. However it was not until the reformation that there was any real rationalisation of churches in Norwich and a significant reduction in numbers. Even this may have occurred more as a result of the valuable location the churches stood on, or their poor state of repair.
However, increasing wealth meant that existing wooden churches were being rebuilt in stone.
Norwich became a city in 1194, when Richard I granted a charter giving rights of self-government
The Black Death came to Norwich in 1349 when as many as two-fifths of the population may have perished. A large proportion of the clergy died, and some parish churches fell into disuse from a lack of priests and parishioners.
Norwich Continued to grow so that in the eighteenth century it was the second largest city in England, surpassing Bristol. Even though there were a large number of independent churches and chapels built in the eighteenth and nineteenth century, the medieval churches continued in use by the Church of England. It is clear that many were neglected and fell into ruin. So chancels were sometimes demolished or towers truncated only for a new incumbent to bring about rebuilding and restoration. Most of Norwich's churches were subject to the Victorian zeal in returning the churches to the appearance the Victorians thought they should have had (even if they hadn’t).
Luckily, unlike the city of London the “zeal” did not leave to destruction indeed only one medieval church was lost in 19th century Norwich i.e. St Peter Southgate.
At the start of the nineteenth century the majority of the population still lived within the medieval city walls. However the increase in population, from about 36,000 to over 65,000 by 1850 and exceeding 110,000 at the turn of the century resulted in extensive house building outside the city walls, whilst large areas within the walls were gradually redeveloped for factories and other commercial uses.
Norwich city centre steadily lost population for most of the 20th century. Slum clearance started early in Norwich. The central area became more and more commercial, and less and less residential.
Enemy action in the Second World War destroyed areas of the city centre, and many others suffered extensive damage.
Today the townscape of Norwich remains dominated by its churches. More medieval churches than any city north of the Alps. The NHCT strive to retain this priceless heritage.
