The largest gold mine of the roman empire

This landscape might look natural, but it is not. At least not at a 100%. What you can see in our picture today is Las Médulas Cultural Park, in León, Spain, an ancient roman gold mining site which was as well the largest open pit one of the whole Empire.

Romans started exploiting it in the 1st century and continued doing so for 150 years at least. They removed more than 500 million cubic meters of earth and transformed the landscape forever. To extract gold they dug a complex system of tunnels inside the hills and then poured water in it to fragment the rock. It is estimated that more than 20.000 people worked in this site.

The exploitation was definitively abandoned in the 3rd century, and from that moment nature recovered what was its own. Oak trees and holm oaks grew again, and hundreds of chestnuts trees were planted. Wildlife includes roe deers, wildcats and boars, among other species.
