There were several stops on the way to the south to check small interesting spots. One of them is the mine São Domingos, where mining took place already under the Roman rule. In 1855, the mine started functioning again till 1966.
Nowadays, the area (railway station) is absolutely ruined, it looks haunted, at the same time it is a fascinating and thought-provoking place. I was walking through ruins trying to imagine what was going on here before, old trains bringing the metals to different destinations, workers suffering from heat and intoxication. The mighty of rich owners and misery of simple people, progress and lack of humanity. What have those walls witnessed? What do they want to tell?
