Carreg PumsaintA miner underground at Pumsaint gold mine Wales; c.1938?.
The name is Welsh for "Five Saints" (Pump being the word for "five"). 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.

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.
That gold occurred here is shown by the discovery of a hoard of gold ornaments in the 18th century. Objects found included a wheel brooch and snake bracelets, so named because they were soft enough to be coiled around the arm for display. All the objects are now held in the British Museum, and displayed in the Romano-British gallery. A sample of gold ore was found at the site by Henry de la Beche in 1844, confirming the presence of gold.
Evidence from the fort (known as Luentinum from details given by Ptolemy) and vicus show that the Romans worked the mine during the first and second centuries AD (from c. AD 78 until around AD 125), judging by the occupation of the fort. However coarse ware and Samian ware pottery recovered from a reservoir (Melin-y-Milwyr) within the mine complex show that activity at the mines continued until the late third century at least. Since Ptolemy's map dates to about 150 AD, it is likely then that it continued being worked until the end of the third century if not beyond. The Romans made extensive use of water carried by several aqueducts and leats (the longest of which is about 7 miles (11km) from its source in a gorge of the river) to prospect for the gold veins hidden beneath the soil on the hillsides above the modern village of Pumsaint. Small streams on Mynydd Mallaen, the Annell and Gwenlais, were used initially to provide water for prospecting, and there are several large tanks for holding the water still visible above an isolated opencast pit carved in the side of the hill north of the main site. The water was used in a method known as hushing, where a wave is released to sweep soil and sub-soil away to reveal bare rock. The method was also used to remove as rock debris after a vein was attacked using tools and fire-setting to produce the opencast. The larger aqueduct from the Cothi crosses this opencast, proving the opencast to be earlier.

Other places of interest include the Red Kite Visitor Centre, located in the Old Coach House in the centre of the village, where displays on the oak woodlands, the traditional nesting place of the bird, may be viewed. To the north up the Cothi valley and across the watershed into the Tywi valley lies the large dam of Llyn Brianne and the wilderness beyond is good pony trekking country.
A leat is the name, common in the south and west of England and in Wales, for an artificial watercourse or aqueduct dug into the ground, especially one supplying water to a watermill or its mill pond. Other common uses for leats include delivery of water for hydraulic mining and mineral concentration, for irrigation, to serve a dye works or other industrial plant, and provision of drinking water to a farm or household or as a catchment cut-off to improve the yield of a reservoir.
A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, decorticating and polishing of grain in agriculture. In mining, trip hammers were used for crushing metal ores into small pieces, although a stamp mill was more usual for this. In finery forges they were used for drawing out blooms made from wrought iron into more workable bar iron. They were also used for fabricating various articles of wrought iron, latten, steel and other metals.
Welsh gold is gold found in natural geological deposits in two distinct areas of Wales and highly prized because of its origin and scarcity.
The Dolaucothi Gold Mines, also known as the Ogofau Gold Mine, are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint, Carmarthenshire, Wales. The gold mines are located within the Dolaucothi Estate, which is owned by the National Trust.
The ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, but transformed by the Romans into a technology inconceivable in Greece. The architecture used in Rome was strongly influenced by Greek and Etruscan sources.
A stamp mill is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation.
Sarn Helen refers to several stretches of Roman road in Wales. The 160-mile (260 km) route, which follows a meandering course through central Wales, connects Aberconwy in the north with Carmarthen in the west. Despite its length, academic debate continues as to the precise course of the Roman road. Many sections are now used by the modern road network while other parts are still traceable. However, there are sizeable stretches that have been lost and are unidentifiable.
Caio is a village in the county of Carmarthenshire, south-west Wales, sited near to the Dolaucothi Gold Mines.
Las Médulas is a historic gold-mining site near the town of Ponferrada in the comarca of El Bierzo. It was the most important gold mine, as well as the largest open-pit gold mine in the entire Roman Empire. Las Médulas Cultural Landscape is listed by UNESCO as a World Heritage Site. Advanced aerial surveys conducted in 2014 using LIDAR have confirmed the wide extent of the Roman-era works.
The technology history of the Roman military covers the development of and application of technologies for use in the armies and navies of Rome from the Roman Republic to the fall of the Western Roman Empire. The rise of Hellenism and the Roman Republic are generally seen as signalling the end of the Iron Age in the Mediterranean. Roman iron-working was enhanced by a process known as carburization. The Romans used the better properties in their armaments, and the 1,300 years of Roman military technology saw radical changes. The Roman armies of the early empire were much better equipped than early republican armies. Metals used for arms and armor primarily included iron, bronze, and brass. For construction, the army used wood, earth, and stone. The later use of concrete in architecture was widely mirrored in Roman military technology, especially in the application of a military workforce to civilian construction projects.
Luentinum or Loventium refers to the Roman fort at Pumsaint, Carmarthenshire. The 1.9 hectares site lies either side of the A482 in Pumsaint and was in use from the mid 70s AD to around 120 AD. It may have had particular functions associated with the adjacent Dolaucothi Gold Mines. It formed part of a network of at least 30 forts across Wales, such as Llandovery, Bremia/Llanio near Llanddewi Brefi, and the fort at Llandeilo. The Roman road Sarn Helen, which runs past the Llanio and Llandovery forts was nearby.
Mining was one of the most prosperous activities in Roman Britain. Britain was rich in resources such as copper, gold, iron, lead, salt, silver, and tin, materials in high demand in the Roman Empire. Sufficient supply of metals was needed to fulfil the demand for coinage and luxury artefacts by the elite. The Romans started panning and puddling for gold. The abundance of mineral resources in the British Isles was probably one of the reasons for the Roman conquest of Britain. They were able to use advanced technology to find, develop and extract valuable minerals on a scale unequaled until the Middle Ages.
Cynwyl Gaeo is a parish and community located in rural Carmarthenshire, Wales, near the boundary with Ceredigion, in the upper Cothi valley about halfway between Lampeter and Llandovery. The population of the village at the United Kingdom Census 2011 was 940. It includes the villages of Caio (Caeo), Crug-y-bar, Cwrtycadno, Ffarmers and Pumsaint.
Ancient Roman technology is the collection of techniques, skills, methods, processes, and engineering practices which supported Roman civilization and made possible the expansion of the economy and military of ancient Rome.
Longovicium was an auxiliary fort located on Roman Dere Street, in the Roman province of Britannia Inferior. It is located just southwest of Lanchester in the English county of Durham, roughly 8 miles (13 km) to the west of the city of Durham and 5 miles (8 km) from Consett.
Fire-setting is a method of traditional mining used most commonly from prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Rapid heating causes thermal shock by itself—without subsequent cooling—by producing different degrees of expansion in different parts of the rock. In practice, rapid cooling may or may not have been helpful to produce the desired effect. Some experiments have suggested that the water did not have a noticeable effect on the rock, but rather helped the miners' progress by quickly cooling down the area after the fire. This technique was best performed in opencast mines where the smoke and fumes could dissipate safely. The technique was very dangerous in underground workings without adequate ventilation. The method became largely redundant with the growth in use of explosives.
Hushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins. A flood of water is very effective in moving soil as well as working the ore deposits when combined with other methods such as fire-setting.
Afon Annell is a small river in Carmarthenshire, Wales.
The Afon Twrch is a short river in Carmarthenshire, West Wales. It joins the River Cothi at the village of Pumsaint, near to which are the Roman gold mines of Dolaucothi.
Mynydd Mallaen is an expansive plateau to the northwest of Cilycwm in northeast Carmarthenshire, Wales. It forms part of the Cambrian Mountains massif, and is north-west of the Black Mountain (range) in the Brecon Beacons. It takes the form of an undulating plateau with steep slopes dropping away to the Towy valley to the east and those of the Gwenffrwd, Nant Melyn and Afon Cothi to the north and west. Its highest point of 1516 feet or 462m at OS grid reference SN 723455 is surmounted by two Bronze Age cairns known as Crugiau Merched. Caeo Forest covers much of the southern flanks of the hill and smaller forests also cover its eastern slopes. Much of the native woodland consists of sessile oak groves, especially on the valley sides. The human population is very low, being restricted to hill farms engaged in sheep farming, and some holiday cottages.
