Maintenance work set to cost around £72,000, is due to start on the historic Custom House at King’s Lynn.
Scaffolding started to go up this week in preparation for work on the timber at the top of the building.
The scaffolding will take around four weeks to erect before the cupola and balustrades at the top of the building are repaired and re-painted.
The maintenance work is expected to take eight weeks to complete, depending on the weather, followed by a further three weeks to remove the scaffolding,
Elizabeth Nockolds, West Norfolk borough council cabinet member, said: “This part of the Custom House is very exposed to the elements particularly, being so close to the river. It is vital that we carry out regular planned maintenance to preserve this iconic and historically important building.”
The light show will be switched off while the work takes place and access to the Tourist Information Centre will be unaffected by the works.
