English Heritage’s Grime’s Graves, identified about 150 years ago as neolithic flint mines, has opened a second pit to visitors who will be winched deep underground to see the 4,000-year-old site where Neolithic miners used antlers to hack out flint.
A challenging descent by ladder, winch and harness into a prehistoric underworld will open to the public for the first time this year, allowing exploration of shafts and galleries cut deep under Norfolk heathland more than 4,000 years ago.
Just 10 prehistoric flint mines have been identified in England and only Grime’s Graves is open to the public. Formerly visitors to the site were only able to go into Pit 1. This year English Heritage will open a second, Greenwell’s Pit, giving a better impression of the original appearance of the shafts. Booking starts this week for visits by English Heritage members from April and for the general public from June.
