Cwm Ystwyth is considered the most important non-ferrous metal mining site in Wales providing a premier example of mining heritage in Ceredigion 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 and the site is a scheduled ancient monument.
