Dinorwic Quarry ceased to be a working quarry in 1969 and is now home to the National Slate Museum. Its workshops at Gilfach Ddu, however, have been preserved and on a wet and very dull September day in Llanberis made for a welcome photographic walk, and a stop for a warm lunch. The quarry face still looms above the workshops and the smell of smoke from the narrow gauge Llanberis Lake Railway filled the air. The interior of the workshops are an interplay of the light that seeps through the gothic windows with stone and metal of the fabric and tools that lie all over the place.
