Lledr Valley facts for kids
The A470 road follows the line of the valley, as does the railway line from Blaenau Ffestiniog to Llandudno, and within the valley there are stations at Roman Bridge, Dolwyddelan, and Pont-y-Pant.
Dolwyddelan is the main settlement in the valley.
During the Victorian period the valley was renowned for its slate quarries, which were concentrated around Dolwyddelan. These quarries worked the Nod Glas Formation, which extended across Mid and North Wales. It was primarily a bed of soft, black shale, but in the area of the Dolwyddelan syncline it was partially metamorphisised into slate. The principle quarries in the valley were:
- Prince Llewellyn quarry and Chwarel Fedw
- Chwarel Ddu
- Ty'n-y-bryn quarry and Penllyn
- Rhiw-goch quarry
