Cerro de los Almadenes, Archaeological site in Otero de Herreros, Spain
The archaeological site stands on a granite dome containing copper veins at the foot of Sierra del Quintanar mountain range in Segovia province.
The Spanish Society of Archaeological History research team has conducted excavations since 2009, uncovering metal furnace structures and metallurgical remains from Roman times.
The Junta de Castilla y León designated Cerro de los Almadenes as a Cultural Heritage Site in June 2022, recognizing its archaeological significance.
Two streams, Arroyo de la Escoria and Arroyo del Quejigal, shape the terrain and determine the location of mine entrances and water channels.
Josef Aparicio Calatrava created the first documented evidence of the site's mineral importance through his drawings of slag deposits in the 18th century.
