"The children loved walking around the site to see where other mine shafts were and how people worked down the mines. There has been so much follow up work based from the trip which has excited the children from written work to art, geography and of course history!"

Amy Dunning, Teacher, North Denes Primary School

Grime's Graves is the only Neolithic flint mine open to visitors in Britain. This grassy lunar landscape of 400 pits was first named Grime's Graves by the Anglo-Saxons, but it was not until one of them was excavated in 1870 that they were identified as flint mines dug over 5,000 years ago. 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: visitors over the age of 7 can descend 9 metres (30ft) by ladder into one excavated shaft to see the jet-black flint.
