The monument comprises the remains of the Cwmafan copper works flue and stack. Copper smelting was established in Cwmafan in 1835, when the foundation stone of the original works was laid. At the time, the Swansea district was the centre of the copper industry. The works first produced copper in 1838 and continued under several different ownerships until it was abandoned in 1906. The flue was constructed to combat the effects of the pollution caused by the works and comprised a culvert that climbed the slope to the west of the works, culminating in a stack situated on the summit. An essay by the Rev John Rowlands (1853) describes the works: The works were sited at the foot of the Foel mountain
