Wales — Industrial Heritage

Wales helped to power the modern world. Its coal, slate, iron, and steel travelled far beyond its borders, fuelling the industries of Britain and shaping lives across the globe. The valleys thundered with the sound of coal mines, the quarries of the north sent slate to roof cities worldwide, and the great steelworks of the south defined communities that still carry their legacy today.

This is a heritage of hard work and innovation, but also of immense human struggle. Entire towns grew around pits and furnaces, their chapels filled with song and solidarity. The landscape still bears the imprint of those times: towering spoil tips, rows of miners’ cottages, and the mighty remains of ironworks and foundries. Today many of these sites are preserved, telling the story of the people who shaped the industrial age.

Wales’s industrial past has been recognised internationally, with the Slate Landscape of North West Wales awarded UNESCO World Heritage status. Elsewhere, the Big Pit National Coal Museum allows visitors to descend into the dark tunnels once worked by generations of miners, while Blaenavon’s ironworks stand as a monument to the ingenuity that transformed raw ore into the foundations of modern life.

This map highlights the places where industry and heritage meet — mines, quarries, canals, mills, and monuments — so that you can explore how Wales’s labour, resource, and spirit helped to build the world.
