Built in 1929 to wind the blondin ropeway from Wern Ifan pit. The quarry opened c1816 when it was worked by William Turner. In 1863 it was bought by W A Darbishire & Co., after which it underwent substantial modernisation, reflected in the use of both water and steam power. During the 1890s about 450 men worked here; it finally closed in 1997.


Single-storey rectangular plan structure aligned north-east to south-west, constructed of roughly coursed slate slabs with gable-ended slate roof. Central window (joinery missing) to front wall with doorway and further window openings in left gable end; integral red brick stack to right gable end.


Retains concrete base for former electric motor which wound the blondin ropeway. On the internal wall are 3 murals, each contained in a painted disc, one depicting a horse's head, the others a bird on a branch and a dog's head with potted plant.
