Bank of Lime Kilns at Pentre Gwenlais Stone Quarry, Pentre Gwenlais Road (NE side)

The Bank of Lime Kilns at Pentre Gwenlais Stone Quarry, built in 1903, is a large masonry structure that features lime kilns with a strongly battered front and right end. The building is constructed from randomly coursed rubble and has red brick semicircular arches over the working areas. Each working area contains a pair of deeply recessed, camber-headed working holes. Originally, there were hoppers at the front for drawing lime directly into railway wagons, and the upper parts of these chutes are still in place. This mechanised loading system contributes to the impressive height of the structure. A walkway runs across the front of the working areas, featuring square-headed tunnels with stone lintels set into the masonry piers. The kilns were loaded from a platform at the top, which still has remnants of a stone parapet. The left end of the structure has been reinforced. Inside, the tall cylindrical kilns are thickly lined with vitrified brick.
