The City wall was built to defend the north and west sides of medieval Norwich. The east side was protected by the River Wensum. They were built in flint between 1337 and 1344 by Richard Spyke at his own expense.
The walls were maintained until the late 18th century at which time the gateways were demolished.
Much of the wall has now disappeared. Buildings gradually encroached on it and sections collapsed or were plundered for building materials. Parts were demolished for redevelopment and road widening.
Today, 15 sections survive above ground. They are amongst the longest city walls in England.
