Grime's Graves Prehistoric Flint Mine - English Heritage

A view of Grime's Graves

Grime's Graves is the only Neolithic flint mine open to visitors in Britain. A grassy lunar landscape of over 400 shafts, pits, quarries and spoil dumps, they were first named Grim's Graves - meaning the pagan god Grim's quarries, or 'the Devil's holes' - by the Anglo-Saxons. It was not until one of them was excavated in 1870 that they were found to be flint mines dug over 5,000 years ago, during the later Neolithic and early Bronze Ages. Today visitors can descend 9 metres (30 ft) by ladder into one excavated shaft, an unforgettable experience.

The small exhibition area illustrates the history of this fascinating site. Set amid the distinctive Breckland heath landscape, Grime's Graves is also a Site of Special Scientific Interest, the home of a wide variety of plants and fauna.

There are currently no toilets on this site.
