National Slate Museum

The former Oil Store, beyond the Engineer’s House, today houses a remarkable 3-D presentation - To Steal a Mountain, which tells the story of the quarry’s development in pictures, words and music which combines in a fascinating introduction to the quarryman’s world. People have been quarrying slate in north Wales for over 1,800 years. It’s a story full of hope and magic as well as sadness and poverty. There are regular showings of To Steal a Mountain in Welsh, French and German and English. Find out more about quarry life and the history of Dinorwig including a slate industry timeline.

Year round demonstrations and talks particularly suited to families include slate splitting demonstrations by our friendly quarrymen and talks about UNA the quarry engine — where you can see how an engine actually works.

Other activities include a specially constructed sand pit in the foundry where you can try to make perfect patterns in the sand like the moulders would have done.

There is an increased programme of family activities during each school holiday including slate decorating, dressing up in the quarrymen's houses and seasonal trails for Easter and Hallowe'en.

Families can also have fun completing a children's passport, the Quarrymen's Houses booklet or the Art Cart booklet. There is a play area for young children including a zip wire!
