Scratchbury & Cotley Hills SSSI (grid reference ST915437) is a 53.5 hectare biological Site of Special Scientific Interest[1][2] at Norton Bavant in Wiltshire, England, notified in 1951. The Iron Age hillfort of Scratchbury Camp occupies the summit of the hill.
The site is protected because of the chalk grassland that supports a large number of species of plants and butterflies. A butterfly species called the Duke of Burgundy has been recorded here[1].
