About the Hackfall Conservation Area
The Hackfall Conservation Area covers about 58 hectares and was designated by North Yorkshire Council in 1993. Inside the boundary are 5 listed buildings (1 Grade II*, 4 Grade II). The most significant is The Ruin, Mowbray Point, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
