Cadw's description
Location
Located to the south-east of the slate mill on Level IV of Pen-yr-Orsedd Slate Quarry above the remains of the incline leading down to the start of the former Nantlle Railway below.
History
Drumhouse of the late 1860s or early 1870s. 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
Drumhouse constructed of sawn slate blocks with gable-ended slate roof. The lower sections of the side walls supporting the drum axle are wider and of more massive construction than the upper sections which support the roof only. Remains of adjoining slate-built structures to south-east and south-west.
Interior
The drum survives with its brake mechanism.
Reason for designation
Listed as a good example of a slate quarry incline drumhouse forming part of a well-preserved group of quarry structures at Pen-yr-Orsedd Slate Quarry.
