Free Entry to Wales's Slate Heritage
The National Slate Museum is housed in the original workshops and power plant of the Dinorwig Quarry (Chwarel Dinorwig), the largest slate quarry in North Wales and once one of the largest in the world. Set on the shores of Llyn Padarn in Padarn Country Park, the museum is free to enter and is the most important collection of slate quarrying heritage in Britain. At its peak in the late 19th century, Dinorwig was producing 100,000 tons of slate annually, employing over 3,000 quarrymen and supporting an entire industrial community.
The museum tells the story of Welsh slate — how it was extracted from the mountain, split into roofing tiles and architectural materials, and exported across the British Empire. It was Welsh slate that roofed London's terraces, lined Manchester's mills, and built the reputation of British craftsmanship in the 19th and early 20th centuries. Between 1843 and 1961, the Padarn Railway transported slate from Dinorwig down to Port Dinorwic on the Menai Strait, from where it was shipped worldwide. The Dinorwig quarry was so productive and such a centre of working-class organisation that it became a focal point for Welsh trade unionism and radical political movements.

The Workshops and Waterwheel
The heart of the museum is the original slate splitting workshop, where you can see the tools and hear the stories of the craftsmen who worked here. The quarry's power is demonstrated by the enormous Victorian waterwheel, which once drove the machinery that split and shaped the slate — a testament to 19th-century engineering and the ingenuity applied to quarrying.
Throughout the workshops, displays explain the quarrying process, from blasting the slate face to the final finishing of roofing tiles. Old photographs, machinery, and workers' accounts bring the quarry's history alive.
Social History and Life in the Quarries
Beyond the technical aspects, the museum explores the lives of quarry workers — their wages, working conditions, union movements, and family life in the slate-mining communities of Snowdonia. The cottages on the site have been restored to show how quarry workers and their families lived.
Special exhibitions rotate throughout the year, highlighting different aspects of slate history, contemporary artists working with slate, and the continuing heritage of slate-splitting as a traditional craft.
