Denorwig

Denorwig, going to try and get up here during my holiday at some point. It about 90 miles away from my home near Llanberis in North Wales.

The main part of the Dinorwic slate quarry complex, at one time the second largest in the world after Penrhyn Quarry. Earlier workings were to the north of this area (see 08) but there is evidence for some working on the present site of the main quarry from 1787. In the course of the nineteenth century these workings were united to form the different departments of Dinorwic quarry, and contour railways and inclined planes laid to connect the rock face with the tips, the slatemakers’ shelters and the mills. The quarry closed in 1969, and part of the lower workings around Hafod Owen have been substantially altered to create the pumped storage scheme.
