Three Lincolnshire buildings have been included on a heritage at-risk list by a national conservation charity.
Save Britain's Heritage has named Sessions House in Boston, Toll House Cottage in Folkingham and St Mary's Guildhall in Lincoln in its annual at-risk catalogue.
The charity said it was campaigning to find new uses for the buildings.
Charity spokesman William Palin said the list was about highlighting empty buildings and promoting their re-use.
"We work very closely with local authorities and conservation officers to identify buildings at risk and to highlight potential problems," he said.
"Sessions House in Boston has been empty since the magistrates court closed three years ago."
Mr Palin said he hoped someone would now come forward with an idea or a viable business use for the building.
"The listed building system will flag up that a building is important and give it some protection - but when a building has been empty for a long time there is sometimes not a lot that can be done.
"So we try to pre-empt problems before a building gets to that stage and find a solution."
Sessions House and Toll House are both Grade II listed buildings and St Mary's Guildhall has Grade I listed status.
