Grime's Graves - Prehistoric Flint Mine

Things to see and do


Enjoy a fun-family day out at Grime's Graves. Pack a picnic, and let little ones blow of steam playing hide and seek in the grassy dips and bumps, or flying kites above. Then follow our family trail and discover why a shark's tooth was found in one of the pits, learn all about Iron Age burials and the animals that would have lived here during the Neolithic period.


Grime's Graves and Breckland is known as 'flint country' and the quality of the flint here has made the area a centre for flint mining throughout history.

The site is home to over 430 mineshafts, extending up to 12 metres underground. These mineshafts, most of which are now covered over, gives Grime's Graves its distinctive lunar-like landscape and has created a unique habitat for many important species of plants and wildlife.
