Ceunant, Nant Ffrancon

SH 63315 64620; 53.16109°N, 4.04585°W

Information

The adit is on the banks of the river Ogwen, close the Arsenic flues. It is now flooded and, at least, partially blocked by various items of rubbish.

Explorations were made at this site in about 1760 by locals, and around 1837 an English company resumed mining activity here, which was stopped because of skin complaints and the pollution of the Afon Ogwen.

Location

Ceunant, Nant Ffrancon

Further Information

These cut-and-cover flues would have radiated from a central point where a furnace would have been employed to produce arsenic from the ore mined at workings close by. The life expectancy of the workers employed in this task would not have been very long! Explorations were made at this site in about 1760 by locals, and around 1837 an English company resumed mining activity here, which was stopped because of skin complaints and the pollution of the Afon Ogwen.
