Roman Gravels Mine

Mining History Feature

Roman Gravels open cut

Background

Roman Gravels lead mine was supposed to have been worked by the Roman invaders before 400 AD, although the mine was initially called Shelfield Gravels.

There are certainly some workings on the mine site of great antiquity, including the "open cuts" on the hillsides (left). These 'hushes' are artificial valleys dug or washed away by ancient miners to expose the veins of galena ore.

Remains of Old shaft pumping and windng engine houses on the hillside above the road in 1985.

In the mid-nineteenth century Roman pottery and tools were found in workings 16m below the surface and the mine became known as Roman Gravels.

A steam pumping engine was installed in the 1780s at Old Shaft, part of the engine house still survives (right). NGR SO 3337 9995.

The Roman Gravels mine achieved peak output in the 1870s when it employed 200 men and had an output second only to Snailbeach. The mine agent (Arthur Waters) installed a compressor at Old Shaft in 1878 to power rock drills in the rich veins along the 65 fathom level - one of the earliest such installations.

Roman Gravels spoil heaps (1985)

All the dressing plant for the mine was on the west side of the Bishops Castle road and until they were removed in the 1990s, there were extensive white spoil heaps of calcite, baryte and quartz here.
