Coed Mawr Pool Lead Mine

Cadw's description

Summary description and reason for designation

The following provides a general description of the Scheduled Monument.

The monument comprises one of the principal dressing floors of a lead mine site which is dispersed around Llyn Pencraig. The mine may have begun as Coedmor, recorded as producing lead before 1697. The site was probably working in the 1750s and was prospering by the 1820s. There was substantial investment after 1851, but the final lessee company at the site was dissolved in 1930.

The scheduled area contains dressing floors associated with production at the eastern end of Llyn Pencraig, where there were shafts and adits. There is a substantial wheelpit for winding at one of the shafts, with a well-preserved bob pit nearby. The hand dressing floors extend over a large area characterised by masses of broken rock and the remains of walls and ore bins. A circular powder store stands on a rocky outcrop where there are also three stone pillars that formerly supported a launder, a trough conveying water to the waterwheel.

The monument is of national importance as a diverse and complex multi-period landscape of hand dressing and ore production, with potential to enhance and illustrate our knowledge and understanding of mining technology. The importance of the site is further enhanced by its group value with other industrial monuments nearby.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive, it is bounded by the trackway at south and east, by a fence line at the north, and by the foot of the slope near the lake edge on the west.
