If you’re a photographer then you can’t come to North Wales without a visit to the awesome Dinorwic Slate Quarry. Dinorwic is a massive former slate quarry now home to the Welsh National Slate Museum . Located between the villages of Llanberis and Dinorwig it was the second largest slate quarry in Wales, in fact in the world, after the neighbouring Penrhyn Quarry near Bethesda. At its peak in the late 19th century, when it was producing 100,000 tonnes of slate, employed more than 3,000 men and was the second largest opencast slate producer in the country. It covered more than 700 acres (2.8 km2) consisting of two main quarry sections with 20 galleries in each and a number of ancillary workings. The site is covered by the remins of an extensive railway network and littered by buildings both big & small.
