Cadw's description
Location
Located to the south-east of the slate mill on Level VI (Bonc yr Offis) of Pen-yr-Orsedd Slate Quarry, the drumhouse is dramatically sited at the head of the incline running downhill to the south-east.
History
Drumhouse built in the late 1860s or early '70s. 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.
Exterior
Consisting of 2 massive battered piers constucted of sawn slate blocks with a gable-ended slate roof; remains of a slate-built structure attached to south-east gable end. The slate-built incline survives in relatively good condition with some rails in situ; a flight of steps runs alongside.
Interior
Drumhouse retains winding drum with brake mechanism.
Reason for designation
Listed as a good example of a drumhouse and incline forming part of the remarkably well-preserved complex of slate quarry buildings at Pen-yr-Orsedd.
