Atocha is a mining city in the department of Potosí, Bolivia, located in the southwestern part of the country near the Argentinean border, at an altitude of about 3,400 meters above sea level. The city's rise and fall are closely linked to silver mining - the Spanish colonizers discovered rich silver deposits here in the 16th century, and in the 19th century it became an important economic center of Bolivia by transporting the ore to Pacific ports via the "Silver Road". Today, Atocha retains its colonial architecture, and the ruins of its pits and old smelting furnaces bear witness to its mining history. Despite the depletion of its silver resources, its unique geographic location and highland landscape make it a gateway for exploring the cultural ecology of southwestern Bolivia, and the surrounding salt marshes and volcanic landscapes provide resources for ecotourism.
