The City's arms are based on a seal of the 15th century. They were recorded and confirmed on 27th May 1562.
The shield depicts Norwich Castle and the royal lion of England. This was traditionally granted to the city by King Edward III (1327-1377).
In past centuries the arms were shown surmounted by a fur cap and supported by angels. These additions were of no authority and are no longer used.
