Mines in Bedfordshire

Bedfordshire's principal historic mining site is Totternhoe, where Roman and medieval quarrymen worked Totternhoe Stone — a hard chalk known locally as clunch — first from open pits and then, from the medieval period, via underground galleries driven beneath Totternhoe Castle that stayed in use until 1925. The stone travelled as far as Westminster Abbey and Windsor Castle, and the site's spoil heaps, now known as Totternhoe Knolls, form a National Nature Reserve today.
