About the Greta Bridge Conservation Area
The Greta Bridge Conservation Area covers about 13 hectares and was designated by Durham County Council in 1987. Inside the boundary are 8 listed buildings (1 Grade II*, 7 Grade II). The most significant is Greta Bridge, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
