Pumpsaint
Coordinates: 52°02′49″N 3°57′40″W / 52.047°N 3.961°W Pumsaint is a village in Carmarthenshire, Wales situated half way between Llanwrda and Lampeter on the A482 in the valley of the Afon Cothi. It forms part of the extensive estate of Dolaucothi which is owned by the National Trust.
Its name means Five Saints derived from the Welsh Pum(p) meaning Five and Saint meaning Saint. The name is derived from the stone block at the nearby gold mines, opposite Ogofau Lodge, which has four sides, each of which has hollows probably caused by pestle impacts. It was used as an anvil for crushing gold ore in the Roman period. Excavations in the 1990s of the area adjacent to the stone showed that the stone was originally horizontal and used as an anvil for a water powered crushing mill. There are many parallels from Spanish mines of the Roman period with similar stone anvils. It is also sometimes known as the Pumpsaint.
The nearby conservation area has several scheduled ancient monuments including the Dolaucothi Gold Mines. Archaeologists have uncovered evidence of Roman occupation of the area, including Roman aqueducts, numerous tanks, cisterns and reservoirs, timber buildings and a fort. There are also extensive underground workings which can be viewed in guided tours organised by the National Trust. Archaeology suggests that gold extraction on this site may have started sometime in the Bronze Age, possibly by washing of the gold-bearing gravels of the Afon Cothi, the most elementary type of gold prospecting. Sextus Julius Frontinus was sent into Roman Britain in 74 AD to succeed Quintus Petillius Cerialis as governor. He subdued the Silures, Demetae and other hostile tribes of Roman Wales, establishing a new base at Caerleon for Legio II Augusta and a network of smaller Roman forts 15 to 20 kilometres apart for his Roman auxiliary units. During his tenure, he probably established the fort at Pumsaint in west Wales, largely to exploit the gold deposits at Dolaucothi. Frontinus later restored the Aqueducts of Rome.
