About the Long Wittenham Conservation Area
The Long Wittenham Conservation Area covers about 27 hectares and was designated by South Oxfordshire District Council in 1970. Inside the boundary are 37 listed buildings (1 Grade I, 36 Grade II). The most significant is Church of St Mary, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
