The Dolaucothi Gold Mines are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint. The gold mines are located within the Dolaucothi Estate which is now owned by the National Trust.
They are the only mines for Welsh gold outside those of the Dolgellau gold-belt, and are a Scheduled Ancient Monument. They are also the only known Roman gold mines in Britain, although it does not exclude the likelihood that they exploited other known sources in Devon in South West England, north Wales, Scotland and elsewhere. The site is important for showing advanced Roman technology.
The history of gold mining at Dolaucothi dates back over two millennia. In around 74AD, the Roman military advanced on this area, quickly establishing a large fort and a gold mining industry that would continue, at one level or another, for around 200 years.
They’d create large open-cast workings and dug several tunnels (adits) to exploit the gold veins. Most of this was achieved using nothing more than picks and hammers in what must have been very hard labour.
They also demonstrated more advanced techniques as they were mining in an area of hard rock, before the age of explosives.
It’s believed that practices such as ‘fire-setting’ and ‘hushing’ would have been used. ‘Fire-setting’ is a process of setting blazes next to rock faces and dousing them with water to fracture the rock by thermal shock. Then ‘hushing’ involved building aqueducts to carry vast amounts of water to the tops of banks. The power of stored water would be released, stripping the top soil and vegetation exposing the ore within the bedrock. This is the technique that’s had the most significant impact on the landscape at Dolaucothi.
Despite the intrusive techniques that were in use by the Romans, what’s significant today is that the undulating woodlands, fields and hills seem timeless; the scars from mining, softened by nature, farming and the passage of centuries.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
