Using a Light Detection and Ranging LiDAR laser device attached to an aircraft, the researchers have identified a larger, more complex system used by the Romans to extract gold in the 1st century BC. It was an ancient Roman gold mine operation that, according to one contemporary record, involved a slave labor workforce of 60,000 men.
8220The volume of earth exploited is much greater than previously thought and the works performed are impressive, having achieved actual river captures, which makes this valley extremely important in the context of Roman mining in the north-east of the Iberian Peninsula,8221 says Javier Fernndez Lozano, a geologist at the University of Salamanca.
8220We have established that the labor that went into extracting the resource until its exhaustion was so intensive that after removing the gold from surface sediments, operations continued until reaching the rocks with the auriferous quartz veins underneath,8221 explains Fernndez Lozano.
According to the research team, this study of ancient Roman gold minesin the Eria valley is the first piece of 8216geo-archaeology8217 performed with LiDAR in Spain.

The Romans extracted gold from mines at Wales, Devon and Cornwall. The price of mining gold took a leap when the Romans developed hydraulic mining in the Spanish mines. Rivers were re-channeled and destroyed. Strabo wrote that this method produced more gold than the deep mines. Some of the Roman mines in Spain were 650 feet deep.

Las Meacutedulas is a natural environment that is considered one of the most singular in Spain.nbsp
Therefore, it was declared World Heritage Site by UNESCO in 1997 and Natural Monument in 2002.
Originally Las Meacutedulas were a mining site. Considered the biggest gold mine built by the Roman Empire, it was abandoned in the 3rd century after extracting 800,000 kg gold.
Thereafter, the native vegetation began to gradually cover the hills of red sand. These hills were formed in Roman times by turning over the interior layers of the earth. Thus, they created galleries in which they injected pressurized water with which they crumbled the slopes of the mountains, bringing the mineral to the surface.
The result is an environment with a beautiful landscape in which the ground has been shaped over time in fanciful reddish formations that contrast with the green of the forest that partially cover them.
There are some spots of great beauty such as the lake of Carucedo it is believed it was made up of stagnant water during mining or the viewpoint of Orellaacuten, from which you can get a good view of this peculiar environment of the province of Leoacuten.
As architectural remains from its industrial and ethnographic past, you can visit the remains of the metallurgic village of Orellan. The vegetation mainly consists of forests of holm oaks, oaks, kermes oak and chestnut.
