This mysterious landscape looks almost lunar thanks to the legacy of years of activity by Neolithic flint miners. This ancient 90-acre site with its strange, undulating mounds and depressions in a woodland clearing is Grime’s Graves, one of the UK’s earliest known industrial sites. In operation from 3000BC to 1900BC, each dip in the land represents a collapsed mine shaft. A ladder and lighting have been installed in one of the best-preserved shafts and visitors can make their way into a chamber from the past to see where miners worked by candlelight.
Grime’s Graves is located on the north side of Thetford Forest park.
