National Slate Museum

The National Slate Museum (previously known as the Welsh Slate Museum and the North Wales Quarrying Museum) is located at Gilfach Ddu, the 19th-century workshops of the now disused Dinorwic quarry, within the Padarn Country Park, Llanberis, Gwynedd. The museum is dedicated to the preservation and display of relicts of the Slate industry in Wales. The museum closed in November 2024 for renovations and will not re-open until 2027. The museum is an anchor point of the European Route of Industrial Heritage (ERIH) and part of Amgueddfa Cymru – Museum Wales.
