National Slate Museum Llanberis

Shadowed by towering slate mountains, the National Slate Museum is housed in the Industrial Victorian Workshops that once serviced and maintained the enormous Dinorwig slate quarry above it. The workshops catered for all the repair and maintenance work demanded by a quarry, which once employed well over 3,000 men. From strikes and suffering to craftsmanship and community, this is an unique opportunity to glimpse the lives of the slate workers and their families.


Attractions & Activities include our stunning introductory film, To Steal A Mountain, daily slate splitting demonstrations by quarry craftsmen and our giant waterwheel – the largest of its kind on mainland Britain. Wander through the Quarrymen’s Houses – re-erected stone by stone at the museum and furnished to show key dates in the slate industry’s history. Step back in time in the foundry or workers’ mess room or why not get all steamed up with UNA – our Hunslet Locomotive – once used to haul rubble in the quarries but now – at over 100 years old – the Museum’s pride and joy.
