About the ST AGNES Conservation Area
The ST AGNES Conservation Area covers about 13 hectares and was designated by Cornwall Council in 1987. Inside the boundary are 43 listed buildings (1 Grade II*, 42 Grade II). The most significant is Church of St Agnes, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
