In the North of the Province of Córdoba, and following the local road CO-5314 that enters the Sierra de Hornachuelos, in the municipality of Posadas we find an old mining exploitation "Las Minas de la Plata", which despite its Abandoned state, it has become an obligatory route for hikers and hikers thanks to its great scenic beauty.
At the foot of the road we find a series of abandoned buildings belonging to the Spanish-German company Sociedad Especial Minera Santa Bárbara, which was responsible for the exploitation of the mine at the end of the 19th century.
These mines, which were already exploited by the Romans, were closed in 1914 due to World War I, since the material obtained was melted down in Belgium and with the war they could no longer be transported to the foundries.
