Hundreds are expected to commemorate the Battle of Britain, starting with a parade by RAF Marham.
They will be accompanied by the Band of the Royal Air Force Regiment to remember the daylight raids, which took place in 1940 after German intelligence indicated that the RAF fighter Command was on the brink of collapse.
The Germans believed that raids would provide the knockout blow needed to gain leverage, instead they had an opposite effect and left the German airforce with 60 less aircraft and a badly shaken morale.
RAF Marham will exercise its Freedom of the City by parading with bayonets fixed.
The parade will start at 11.30 in front of city hall in Norwich and road closures will be in place.
Road closures
The whole of St Peters Street and the part of Bethel Street from where it joins St Peters Street up to The Forum Car park (access to the car park will be maintained during this time) will be closed from 7am until 1pm.
There will be no loading or parking on St Giles from the point it joins St Peters Street up to St Giles multi-storey car park from 7am until 1pm. Vehicles leaving St Giles Carpark during this time will be able to exit as normal, but will not have access to St Peters Street and will need to exit via Gaol Hill.
Visitors to City Hall will not be able to use the main entrance on St Peters Street from 11am until 12.30pm and so are advised to use the customer centre entrance on Bethel Street during this time.
