Portugal, Alentejo, Sao Domingos Mine – October 2016

The Romans mined in the São Domingos area for gold and silver for about 400 years. In 1855 mining was resumed, as the international demand for copper grew during the Industrial Revolution.
About 25 megatons of ore had been extracted when the mine was closed in 1966.
