About the Aldbrough St John Conservation Area
The Aldbrough St John Conservation Area covers about 17 hectares and was designated by North Yorkshire Council in 1975. Inside the boundary are 17 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
