Dinorwic Quarry includes the remains of the Braich levels of the Dinorwic Slate Quarry which operated from around 1770 to 1969. Many of the levels remain intact following the construction of Dinorwic Pumped Storage Power Station (NPRN 408885). The series of `A? inclines from Gilfach Ddu (NPRN40559) and the Anglesey barracks have been scheduled and preserved.

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.

In 1972 the site opened to the public as a museum. Equipment was collected from other slate quarries and parts of the site were restored. It is now the National Slate Museum and part of the National Museum of Wales.
