Cerro del Hierro

The karst formation features limestone rocks with iron deposits, creating a network of corridors, sinkholes, caves, and natural spires spanning 121 hectares.

The site operated as an iron mine from Roman times until the mid-20th century, with Scottish company William Baird Mining extracting 7.63 million tons between 1895-1932.

The iron extracted from these mines provided materials for notable structures in Seville, including the Royal Tobacco Factory gates and Isabel II Bridge.

The natural monument contains over 120 climbing routes of varying difficulty levels, making it the primary climbing destination in Sevilla province.

During autumn and winter rains, temporary lagoons form throughout the karst landscape, supporting populations of amphibians, eagle owls, and black storks.
