In the 1950s, a dolerite quarry was opened up on the east side of Hunneberg. There was strong opposition to the quarry, as it would mean an ugly scar on the silhouette of the mountain. Nevertheless the government approved a permit to quarry dolerite for hardcore, to provide aggregate for making concrete and for road building.
This stone is from the same prehistoric quarry where the oldest monoliths at Stonehenge were sourced. It is a bluestone called Preseli Spotted Dolerite after the Preseli Hills of Wales where the stones were quarried, and where we recovered these fragments.
