About the MILDENHALL Conservation Area
The MILDENHALL Conservation Area covers about 26 hectares and was designated by Wiltshire Council in 1977. Inside the boundary are 14 listed buildings (1 Grade I, 13 Grade II). The most significant is Church of St John the Baptist, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
