Riotinto-Nerva mining basin, Historic mining area in Huelva province, Spain.
The Riotinto-Nerva mining basin is a mining area in Huelva province spanning multiple municipalities and rich in copper and iron minerals. The region consists of active and abandoned mines, processing plants, and settlement structures that reflect centuries of intensive extraction.
Mining in the region dates back to Roman times, but was transformed into large-scale modern production during British management starting in the 19th century. This period led to population growth and made the region one of Europe's major mining centers.
The mining settlements display British architecture and infrastructure that still shape the everyday landscape. Visitors can see former managers' houses, worker neighborhoods, and railway structures that organized the social life of the mining community.
The area is most accessible by car since sites are spread across different roads. It's wise to allow time to visit multiple points, as walks through abandoned mine areas require reasonable fitness levels.
The Rio Tinto river flows through the area with reddish waters created by high mineral concentrations, forming layers of iron oxide deposits. This phenomenon occurs naturally from the rock chemistry and is seen in few places worldwide.
