Grimes Graves

Details

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 10 years of age are not allowed into the mine shaft and visitors should be advised to wear sensible flat shoes.
