Rio Tinto Pier, Industrial dock and monument in Huelva, Spain.
Rio Tinto Pier extends more than a kilometer along the Odiel River, combining sections that span over water with parts anchored in filled marshland. The structure connects the mainland to the river and stands as a notable engineering accomplishment from the late 1800s.
The pier was built between 1874 and 1876 by British engineers for the Rio Tinto Company to transport copper ore to ships. The project marked the beginning of the port's major industrialization and made the location one of Europe's leading ore export points.
The structure shows how British engineering transformed this place into a major port for mineral exports, moving it away from its fishing village origins. Walking along it today, you can still sense the industrial power that shaped the region.
The site is open to the public and offers walkways along the river with views of the natural park. Best times to visit are early morning or late afternoon, when the sun does not shine directly on the exposed sections.
The structure used a gravity system where loaded wagons rolled downhill to ships without mechanical power, moving enormous quantities of ore. This ingenious transport method was simple and reliable, shaping daily port operations for decades.
