A north-east road is closed while emergency repairs are carried out.
Market Place in Inverurie is shut for the works, which are taking place at the town hall.
They are expected to be finished tomorrow.
An Aberdeenshire Council spokesman said: “During the high winds at the weekend, a number of the finial features on Inverurie Town Hall’s cupula became dislodged.
“Market Place has now been closed and fencing erected around the main entrance to the Town Hall to allow emergency inspection work to be carried out and ensure public safety.
“It is hoped the work will be completed tomorrow to keep disruption to a minimum.”
