Dinorwig

Dinorwig is a small village located high above Llyn Padarn, near Llanberis, in Wales.

It is thought that it was part of the territory of the Ordovices tribe, and that 'Dinorwig' means "Fort of the Ordovices".

The village has a long history of slate quarrying. The Romans used local slate for the construction of Segontium, and slates from the valley were used in the construction of Caernarfon Castle. The main local quarry was the Dinorwic Quarry, which was worked from the late 1770s until 1969.
