Dinorwic Quarry & Quarry Hospital

Gilfach Ddu
Llanberis LL55 4TY


Covering more than 700 acres, Dinorwic was one of the largest slate quarries in the world. One of its inclines has now been restored to pristine working condition. Since 1972 Dinorwic has been home to the National Slate Museum, Llanberis. The Vivian Slate Quarry is now home to a rock-climbing and diving centre, but visitors today may still see the huts or gwaliau (literally 'lairs') where blocks of slate were split and dressed. Another site of interest is the old Quarry Hospital, built in 1860 to offer quarrymen medical care. Now open to the public, it features a display of the innovative equipment used there, including amputation tools and an X-ray machine.
