Stonea Camp is an Iron Age multivallate hill fort at Stonea near March in the Cambridgeshire Fens, situated on a gravel bank just 2 metres above sea-level, making it the lowest hill fort in Britain[1]. Around 500 BC, when fortification began at this site, the elevated gravel ridge would have provided a significant area of habitable land amidst the flooded marshes of the fens[1]. The site exhibits at least two phases of development over several hundred years of settlement, with a D-shaped inner set of earth banks surrounded by a larger, more formal multivallate system of banks and ditches[1].
