Grime’s Graves is the only Neolithic flint mine open to visitors in Britain. This grassy lunar landscape of 400 pits was first named Grim’s Graves by the Anglo-Saxons. It was not until one of them was excavated in 1870 that they were identified as flint mines dug over 5,000 years ago.  A small exhibition area illustrates the history of this fascinating site. Visitors can descend 9 metres (30 ft) by ladder into one excavated shaft to see the jet-black flint. Set amid the distinctive Breckland heath landscape, Grime’s Graves is also a Site of Special Scientific Interest and a habitat for rare plants and fauna. Please note that children under 5 years of age are not allowed into the mine shaft and visitors should be advised to wear sensible flat shoes.
