They discover a Roman gold mine in Galicia

A roman gold mine in A Mariña, which can extend over 150 hectares. In Foz, two citizens of the region stumbled upon the existence of a moat while collecting mushrooms. It was an extensive succession of parapets followed by moats that seemed to have no end. For this reason, Manuel Miranda, one of the two hikers and spokesman for the Mariñapatrimonio collective, began to inspect the toponymy of the land upon his arrival home.

The members belonging to Mariñapatrimonio, through the indications of Manuel Miranda, checked the area and discovered other signs such as the piled-up boulders, which could belong to the dumps that the Romans left behind after exploiting the mines. For this reason, they tried to carry out an aerial exploration that did not have the expected success, since the area had been repopulated by pines and eucalyptus trees that barely allowed the ground to be seen from the air.

However, thanks to some images found from the year 56, in which the repopulation process had not yet been carried out, they managed to observe the existence of furrows that flowed down the slope into larger channels.

Suspecting that what they had seen could be a mine, they called the archaeologist Santiago Ferrer and his response was firm, it was a Roman gold mine with its channels, ponds and deposits for washing and decanting the mineral. When observing the aerial photographs, it could be around 150 hectares distributed between Foz and Barrieros, this would mean that it would be the largest gold mine in Galicia and the only one found so far that was washing the gold in the direction of an estuary and not a river.

According to Santiago Ferrer the only thing that can be assured so far is that the mine is in good condition and that its activity could be situated between the 1st to 3rd centuries, being later abandoned by a fluctuation at the drop in the price of the mineral, not because the gold runs out.

Miranda has described the mine as “a beastly engineering feat”. The mine is located surrounded by 20 settlements as a result of the existence of a point that gave labor activity and fed the labor force. The engineers who directed its construction are thought to be from the Legio VII Gemina, that is, of León.

I was born in Madrid on August 27, 1988 and since then I started a work of which there is no example. Fascinated by both numbers and letters and a lover of the unknown, that is why I am a future graduate in Economics and Journalism, interested in understanding life and the forces that have shaped it. Everything is easier, more useful and more exciting if, with a look at our past, we can improve our future and for that… History.
