Step back in time at the National Slate Museum, and uncover the secrets of slate and the people who quarried it here from the 1800s to 1969 at Dinorwig Quarry, Llanberis, Snowdonia.
Just North of the museum is one of the most interesting features of this Satellite Oddity, is the Slate quarry, and the slate waste that covers an entire mountain.
From Virtual Globetrotting:
"The National Slate Museum (previously known as the Welsh Slate Museum) is located at Gilfach Ddu in the 19th-century workshops of the now disused Dinorwic slate quarry, within the Padarn Country Park, Llanberis, Gwynedd.
The museum is an Anchor Point of ERIH, The European Route of Industrial Heritage and part of National Museum Wales." Text Source: (

"Commercial Quarrying began at Dinorwig in the early 19th century. Railways worked by dozens of small steam locomotives transport the slate from Dinorwig to the sea at a harbour known as Port Dinorwic. The quarry closed in 1969 and is now a major tourist attraction.
The National Slate Museum ensures the 3000 men who once worked the quarries are remembered as do the quarry workings which have laid open the side of the Elidir mountain nearby.
The National Slate Museum holds one of the largest water wheels built by Victorian industrialists. The De Winton company of Caernarfon built the 15.4 metre diameter wheel, in 1870. Water to power the wheel was piped down from the slopes of Snowdon in cast iron pipes and its power drove the machinery to produce slates for roof all over Industrial Britain. It remained in operation until 1925, when a smaller, more efficient model substituted it. Such is progress!" Text Source: (
