Cissbury Ring is the largest hill fort in Sussex, the second largest in England[5] and one of the largest in Europe overall, covering some 60 acres (24 hectares).[6] The earthworks that form the fortifications were built around the beginning of the Middle Iron-Age possibly around 250 BC[7] but abandoned in the period 50 BC - 50 AD.
The site of the fort contains a Neolithic mine, one of the first flint mines in Britain. Around 270 shafts were dug into Cissbury hill over around 300 years of use. Shafts were up to 12 metres (39 ft) deep with 7 metres (23 ft) diameters at the surface. Up to eight galleries extended outwards from the bottoms of the shafts, often interconnecting with one another. The site has been damaged by illicit metal detecting.[8]
