Dinorwic quarry also known as Dinorwig quarry is a large former slate quarry, now home to the Welsh National Slate Museum, located between the villages of Llanberis and Dinorwig (formerly Dinorwic) in Wales. At its height at the start of the 20th century, it was the second largest slate quarry in Wales (and thus, the world), after the neighbouring Penrhyn quarry near Bethesda.Dinorwic covered 700 acres (283 ha) consisting of two main quarry sections with 20 galleries in each. Extensive internal tramway systems connected the quarries using inclines to transport slate between galleries. Since its closure in 1969, the quarry has become the site of the National Slate Museum, a regular film location, and an extreme rock climbing destination.
