Mina de San Miguel, Archaeological site and former mine in Almonaster la Real, Spain
Mina de San Miguel is a former mine with both open-pit and underground sections plus processing facilities in Huelva province. The site displays extraction areas and infrastructure that was used for on-site mineral processing.
The site originated during Roman times when it was worked for silver. In the 19th century, French engineer Ernest Deligny revived operations, launching a new phase of exploitation.
The site shows how mining shaped daily life in the region and reveals the different techniques workers employed over time.
The site is fairly remote and takes time to explore properly, so come prepared with water and sturdy clothes. The area is hilly and access to the old mines is not always easy to navigate.
The complex changed hands multiple times, including Portuguese and British ownership, before final closure in 1981. This shifting ownership history reflects the international interests that shaped mining in this region.
