The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon.
The slate industry grew slowly until the early 18th century, then expanded rapidly until the late 19th century, at which time the most important slate producing areas were in northwest Wales, including the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried.
The slate industry dominated the economy of north-west Wales during the second half of the 19th century, but was on a much smaller scale elsewhere.
The slate industry in North Wales is a World Heritage Site, whilst Welsh slate has been designated by the International Union of Geological Sciences as a Global Heritage Stone Resource.

The Penrhyn Slate Quarry, seen here c. 1900, was one of the two largest quarries in Wales.
