Chimney

The Llanrwst Lead Mine chimney, built in 1876-7, is a Grade II listed structure that highlights the historical significance of lead mining in the Gwydir Forest. The mine was established to exploit rich lead deposits, with earlier workings on the site known as the Bwlch-yr-Haiarn mine dating back to the 18th century. The mine operated until around the beginning of the Great War, and while all other buildings have fallen into ruins, the chimney remains intact. It was constructed to provide a through-draught for the boiler-house fire and is located in the northwest corner of the former boiler-house, adjacent to the ruined engine house that originally housed a 25-inch cylinder horizontal condensing engine made by the Sandycroft Foundry Co. in Deeside.

The chimney is cylindrical, standing 18 meters high with a noticeable lean to the west. It is built on a rubble plinth and features rubble construction for the lower two-thirds, while the upper section is made of red brick, culminating in oversailing courses at the corniced top. There is a small brick-arched vent on the west side at ground level.

This imposing chimney serves as a testament to the once-thriving lead mining industry in the Gwydir Forest and is exceptional in North Wales for its surviving relationship with the boiler-house and engine room.
