National Slate Museum
About
The National Slate Museum, situated in the picturesque village of Llanberis within Padarn Country Park, occupies the historic 19th‑century workshops of the former Dinorwig slate quarry. Since its opening in 1972, the museum has offered visitors a detailed look at the industrial heritage and everyday life of Welsh slate workers, showcasing artefacts, machinery and interactive displays such as the "Timber Trail" digital trail and slate‑splitting demonstrations. In November 2024 the museum closed for a major redevelopment programme and is scheduled to reopen in 2026, during which construction work will transform the site to better showcase its rich history. Once back in operation, visitors can explore the museum’s extensive collections, hear the story of slate through talks and demonstrations and marvel at the Victorian workshop buildings set against the backdrop of Snowdon. The museum is a key stop on the European Route of Industrial Heritage and forms part of Amgueddfa Cymru – Museum Wales. Its setting in the shadow of Elidir mountain and proximity to the Llanberis Lake Railway make it a unique destination for those interested in Wales’s industrial past and natural beauty alike. When the museum reopens, it will offer opportunities for visitors to learn about slate quarrying, industrial design and local community life. Until its reopening, access to the site is temporarily closed to the public; however, the museum’s website remains active and welcomes visitors to join mailing lists or receive updates on redevelopment progress. Future visitors can anticipate a richer, more interactive experience that highlights the site’s original workshops, artwork, and the iconic waterwheel.
