Repairs costing £500,000 being carried out on Shire Hall in Chelmsford are set to be completed in the next few weeks.
Scaffolding on the front of the grade 2 listed building will be removed in the coming days and scaffolding on the west side will be taken down by the middle of November.
The works on the Georgian building, which started in April, were subject to a detailed review and consultation process, including obtaining listed building consent from English Heritage.
Essex County Council cabinet member and ward councillor, Cllr Dick Madden, said: "I welcome the news this essential maintenance work at Shire Hall to address the deterioration of its outer fabric is virtually complete and on schedule.
"This is a much-loved building and we have used the best contractors and craftsmen to make sure the work is of the highest quality to preserve and enhance the character of this wonderful building."
The priority works on the building that is situated next to Chelmsford cathedral included conservation stone repairs, cleaning stone surfaces, an overhaul of the metal and timber windows and general maintenance work.
