With the Bank Holiday weekend underway, Culture Secretary Lesley Griffiths has visited the National Slate Museum in Llanberis to see how redevelopment work is aiming to turn the venue into a world-class visitor attraction and has encouraged people to visit.

Welsh Government funding of more than £1m has already helped progress the redevelopment, including maximising museum space for collections and activities and ensuring there is appropriate office space for employees.


The Museum has also secured funding from the National Lottery Heritage Fund to continue redevelopment plans as a main interpretation site for the Slate Landscape of Northwest Wales UNESCO World Heritage Site, including the aim of developing new creative spaces.

Based at the foot of what was one of the largest slate quarries in the world, Dinorwig Quarry, the museum is housed in what were the original engineering workshops, built in 1870, which once employed well over 3,000 workers.

The quarry closed in 1969 before reopening as a museum in 1972. It was redeveloped in 1999 with new facilities and plans for a further redevelopment are progressing.

Cabinet Secretary for Culture and Social Justice, Lesley Griffiths said: “The Bank Holiday presents a great opportunity for people to visit our museums and learn more about the incredibly interesting stories they have to tell.

“The slate industry is an important part of the communities, landscapes and heritage of this part of Wales and the National Slate Museum offers a unique opportunity to glimpse into the lives of the slate workers and their families.

“I have been very impressed with what I’ve seen, and I am pleased the Welsh Government, along with the National Lottery Heritage Fund, has been able to provide funding towards its redevelopment and ensure it continues to offer great experiences for all visitors.

“I would encourage everybody to visit the Museum and learn more about the fascinating history of the area’s slate industry.”


Chief Executive of Amgueddfa Cymru, Jane Richardson said: “We were delighted to welcome Cabinet Secretary for Culture and Social Justice, Lesley Griffiths MS to Amgueddfa Lechi Cymru – National Slate Museum, to show the breadth and depth of our work in north Wales and the innovative ways we can tell the story of slate.

“We’re excited to work with the Welsh Government and our partners, Cyngor Gwynedd and National Lottery Heritage Fund, as we redevelop the Museum into a UNESCO World Heritage site hub.

This transformational project will allow us to create spaces to support traditional skills, learning and wellbeing and better connect with everyone, from local communities to those from further afield, enabling them to find their story through our national collection.”

Arguably the least harmful and environmentally friendly extractive industry…?

Labour relations, parliamentary power and secondary investments etc notwithstanding…

Not so good for workers, pneumoconiosis, COPD.
Pollution aspects under researched but quarries and waste release metals into water courses, aluminium and copper, both toxic to aquatic animals. But definelty not the worst by a long way.
But great for zip lines and great fun..

Dorothea Quarry in the Nantlle Valley, for those not familiar, is the most awesome place and would keep Tom Cruise spellbound….
