Since ancient times, the areas of the Medio Campidano and of Arbus were exploited beacause of the presence of copper, silver and lead ores. But, it’s during the 19th century that the most important mines started to work and their remains are still visible. The mining sites of Ingurtosu and Montevecchio can be visited and they are both included in the Mining Geopark of Sardinia. These places are now impressive examples of industrial archaeology, silent witnesses of people who lived and worked there.
