Caynham Camp, near Ludlow in Shropshire, is one of a number of hill forts constructed between about 800BC and 100BC along the border between England and Wales.
It is a univallate structure - surrounded by a single defensive bank - and stands 174 metres above sea level.
Local tradition says that Parliamentarian forces used Caynham as a base before their attack on Royalist-held Ludlow Castle in 1646.
Between the 17th and early 19th centuries, limestone was quarried from the northern side of the hill and burnt to make quicklime for building and improving the soil.
