Today, City Hall was subject to an act of vandalism.
A spokesperson for Norwich City Council said: “This act of vandalism is totally unacceptable. It has been reported to the police and they are now investigating the matter.
“Vandalism and destruction can never be justified. Such acts immediately undermine any coherent argument being made.
“The bronze doors of City Hall are a work of art which depict the history, trade and industry of the city. The damage to them and the surrounding stonework of the Grade II* listed building is extensive.
“We will need to bring in specialists to advise us on how to proceed with restoration work. There will inevitably be a considerable cost to this.”
