Grime's Graves

Grime's Graves is a large Neolithic flint mining complex in Norfolk, England, located 8 km (5 mi) north-east of Brandon, Suffolk [1]. The site was worked between approximately 2600 and 2300 BC, though production likely continued through the Bronze and Iron Ages due to flint's low cost compared to metals [1][2]. The flint extracted was primarily used for making polished stone axes during the Neolithic period [1]. Later uses included building materials and musket strikers after metals replaced flint for tools [1][2].
