This small town is very important for the history of San Luis Potosí, since it was for the discovery of these mines that gave rise to the State Capital.
These constructions now only house memories of another time, inhabited by cactus and biznagas that grow to the sun and the wind. The silence and the howling blizzard are the best guide when visiting the ghost town of San Pedro.
The wealth produced by the mines in the first thirty years became legend; People came from all the trades of miners as well as numerous merchants who enriched and returned to Spain.
The mines were exploited, among other companies, by ASARCO, Metalúrgica Mexicana. In the period of the latter a mining strike was raised (1948), which was lost by the miners; the company decided to leave, not without first collapsing the mines. Their mines were never declared exhausted.
Now as Patrimony of the Nation, it is great for a walk in silence, to delight the view and to unravel the roots of their stories.
