Dinorwic Quarry History

Dinorwic Quarry was once a site bustling with activity and thousands of workers, and then the second largest quarry in the world.

It would be fair to say that the slate quarried at Dinorwic in the 1800’s helped to roof the world.

The quarry was owned by the Assheton-Smith family and later another branch of the same family called Duff.

Many of the quarrymen came from the local area. However, some men travelled across from North Wales to work at Dinorwic.

A large number came from Anglesey, and in the 1800’s a man’s journey from Anglesey could start at 3am. It would involve a 10 mile walk, a ferry crossing, a further walk, a train journey and finally a climb up to the rock face.

Travelling to Dinorwic at the beginning of the week was tough enough, even before the days work began. 

Those who travelled from other parts of Wales often stayed on site during the week and travelled home to see their families at the weekend.

From the 1920’s buses were introduced and transport to and from the quarry became a lot easier for the workers.

Including the quarry itself, the complex covered an area of roughly 1km x 500m. 

Dinorwig remained under the ownership of the same family until its closure and sale in 1969.

What To Expect At Dinorwic Quarry In Wales

Now home to the Welsh National Slate Museum, a Dinorwic Quarry walk can be an interesting way to spend an afternoon in Wales.

We visited after our trip to Aber Falls on our Wales itinerary, and starting from the car park, you simply follow the trail to Allt Ddu.

Allt Ddu was part of the Dinorwic quarrying area which was operating prior to 1771, and the route many workers would class as the ‘entrance to their workplace’.

You can then follow the Dinorwic Quarry walking route up to Ardal Mills, a building that once housed one of Dinorwig’s slate mills. It covers the same area as two football pitches and its size reflects the ambitions of the quarry owners.

The mills were unpleasant places to work. They were cold and covered in dust. In fact, there were so many accidents at Dinorwic that from the 1860’s the quarry had its own hospital.

Follow the trail some more until finally you’ll arrive at the Dinorwig viewpoint. This viewing point will give you spectacular views over Anglesey and Llanberis and then up to Snowdon.

When the quarry shut in 1969 all the equipment was auctioned off. The small steam locomotives were all sold for preservation but there was little interest in the rest of the machinery or buildings.

Consequently, there is lots left to see around the 700 acre site, including old miners cottages, rail tracks and rusted machinery. 

The National Slate Museum is a living working museum housed in the industrial Victorian workshops that once serviced and maintained Dinorwic Quarry.

The museum is worth a visit to get an idea of the history of Dinorwic Quarry before walking through it. Open 10am – 4pm Sunday to Friday. Entry is free.

Next up on the Wales itinerary was a big drive down the West coast to Llangrannog Beach.
