Minas de hierro de Alquife Historical milestone · Alquife, Comarca de Guadix, Granada Worked since the 19th century, the Scottish Bairds Mining Company acquired the concessions in 1895; after the handover to the Compañía Andaluza de Minas in 1929 and peak production between 1940 and 1970, the mines closed between 1996 and 2021, when they reopened due to high steel prices. They form the largest open-pit iron mine in Europe, with an underground lake up to 130 meters deep. 1996-2021 Photo: ricardo lago (CC BY-SA 2.0) What to see and do in Alquife
