Site Description

Dinorwic Quarry includes the remains of the Braich levels of the Dinorwic Slate Quarry which operated from around 1770 to 1969. The surviving remains of the site include four substantial counterbalanced inclines, complete with rails, sleepers and drumhouses, a weighbridge house, locomotive sheds, water tanks and an office and caban. There is also a blondin with winding house and an electric compressor house. There is a large slate mill with two integral engine houses and saws, catslide extension and smithing hearth.

The site is now home to the National Slate Museum.
