Parc Mine
Parc Mine is located in the Gwydir Forest within the Snowdonia National Park, approximately 1.6km southwest of Llanrwst and approximately 5km north of Betws-y-Coed. Parc Mine was worked sporadically from 1855 to 1963, recovering over 10,000 tons of lead and 4,000 tons of zinc. The mine is interconnected via its underground workings with eleven other mines, and sits in close proximity to numerous other independent mines such as Hafna Mine and Pandora Mine. When the mine...

Bu gwaith achlysurol ym Mwynglawdd Parc rhwng 1855 a 1963 a chloddiwyd dros 10,000 tunnell o blwm a 4,000 tunnell o sinc. Trwy ei weithfeydd tanddaearol, mae’r mwynglawdd yn cysylltu ag un ar ddeg o fwyngloddiau eraill, ac mae'n agos iawn at nifer o fwyngloddiau annibynnol eraill fel Mwynglawdd Hafna a Mwynglawdd...

Wemyss Lead & Zinc Mine
The abandoned Wemyss Mine is 15km southeast of Aberystwyth, Ceredigion. It is located at the head of the Cwmnewydion valley, a tributary of the River Magwr, which joins the River Ystwyth at Abermagwr. The mine worked the Frongoch mineral lode alongside Frongoch and Graig Goch mines. Wemyss became an integral part of the larger Frongoch Mine and cannot be considered in isolation from its more illustrious neighbour. In the 1840s both mines came under the same...
