Bwlch y Slaters quarry, Slate quarry in Gwynedd, Wales.
The quarry spans across steep terrain near Blaenau Ffestiniog, featuring old mills and workshops used for slate processing and transportation systems.
Starting operations in 1780s near Manod Mawr summit, the quarry developed significantly in 1866 when connected to the Rhiwbach Tramway for slate transportation.
The site represents Welsh industrial heritage, where generations of workers extracted and processed slate using traditional mining techniques and transport methods.
Visitors can access the quarry through marked paths, though remote location requires proper hiking equipment and attention to weather conditions.
During World War II, the National Gallery stored its art collection in this quarry, where conditions proved better for artwork preservation.
