The Romans found gold here at Dolaucothi in south Wales, near the village of Pumsaint, in 74 A.D. During five centuries of mining, Roman engineers developed hydraulic works, then a large open pit mine, and eventually vast underground operations, complete with dewatering channels and pumps to keep deep mine tunnels from flooding.

Beginning in the nineteenth century, the British made several tries at reopening the mine, but they gave it up for good in 1938, defeated not so much by lack of gold as by surfeit of water underground. Today, Dolaucothi is a national park, offering mine tours and archaeological exhibits of Roman artifacts found onsite.
