A key heritage site in the heart of the city is set for some upgrades.

The Guildhall, in Gaol Hill, is England’s largest medieval city hall and was the centre of city government until it was replaced by City Hall in 1938.

Plans submitted by Norwich City Council are intended to upgrade the roof fall arrest system, a barrier designed to stop the fall of any maintenance workers on the roof, as well as a wire system and shock absorbers.

The proposal has been approved, even though the plans could cause a "level of harm" to the historic site.

"It is considered that the proposal offers a level of harm to the overall significance of the grade I listed building," read the officer report from the city council.

However, planning officers decided that the level of harm was mitigated by the need to create safe access to the roof for future maintenance.

Historic England was approached but did not offer advice.

The city council has been granted three years to complete the work.
