Cwmystwyth is considered the most important non-ferrous metal mining site in Wales providing a premier example of mining heritage in Ceredigion. Within the site there is evidence for all phases of mining activity; from the Bronze Age, through the medieval period, to its revival in the 18th century and the peak of activity with a subsequent decline in the late 19th and the early 20th century. It has been designated as a Scheduled Ancient Monument. Silver, lead and zinc have been mined in the valley of the River Ystwyth since Roman times, an activity that reached its peak in the 18th century. The largest of the very many mines was the Cwmystwyth mine. The mine, with its amazing bronze age finds, lies up the valley from the cottages and the mines themselves are fenced off for safety. The Silver Mountain Experience nearby at Llywernog, Ponterwyd SY23 3AB is great for families.
