The Rio Tinto Pier ( es, Muelle de Rio Tinto) was a commercial pier formerly used for the trade of material from the mines of the Rio Tinto Company in Andalusia, Spain. It is situated on the River Odiel in the city of Huelva. An estimated 150 million tons of ore were shipped from the pier over its life. Closed in 1975, it is now a popular tourist attraction and fishing spot. The pier is 1165 meters long, although part of that is built on reclaimed marshland.

History

A site along the Rio Tinto had been mined since 3000 BCE. Over time, mining activities fell into neglect, until 1724 when the Spanish government began mining again. However, mining operations were inefficient, and the government itself was distracted by political and financial crises, leading it to sell the mines by auction in 1873.The syndicate purchasing the mine was led by

and, following purchase of the mine, the buyers launched the Rio Tinto Company. At the end of the 1880s, control of the firm passed to the

, which greatly increased the scale of mining operations. The company needed to get the ore produced at the mines to Britain, so in the two years after purchase an 83-mile railway was built, following the course of the Rio Tinto, with four tunnels and ten bridges. This connected with the company's own pier at Huelva. The construction of both the railway and the wharf required British expertise and British troops were used to protect the workers. The mine and the choice of Huelva as the port had a significant impact on Huelva, which went from being a small fishing village to the world's leading port for copper exports. The pier was designed by the engineers, Sir

in India. It had two platforms. Ore-bearing trains ran on the upper platform and general goods trains to import supplies for the mine ran on the lower platform. There are many structural elements, some of which were added at a later stage to repair and reinforce sections of the dock. A characteristic that distinguishes this pier from the others of its time is that its foundation is on wooden platforms at the bottom of the estuary. The Rio Tinto pier began with an initial 238-meter section formed by an earth embankment built on concrete and brick. For the next 225 meters, still on reclaimed land, it is on a wooden viaduct. From this point it stands on double rows of four cast iron pillars (60 rows of four pillars). When entering the river, it continues for about 200 meters at right angles to the bank and then forms a broad curve with a radius of about 200 meters, culminating in a new straight section of about 170 meters oriented in the direction of the current and the tides. In total this iron section was 577.6 meters long, although in 1974 about 50 meters of it was destroyed to make way for road widening. MuelleRioTintoSunset

The railway wagons reached the ships at the end of the pier using gravity. This consisted of arranging different ways of entry and exit of wagons to and from the wharf. Those going on to the pier descended from the top of the beginning of the pier to the end of the jetty. Following a change of

, the wagons return via a line that was also descending. Therefore, the unloading of the trucks was done without any mechanical system.

Restoration

The pier remained in service until May 1975 when ships began to use a new facility in the nearby port of Huelva. Soon after that a section was removed to make way for widening of the road that goes along the river and the pier was effectively abandoned and fell into decline. In 1980 a contest was held for the reuse of the dock, but none of the ideas presented has ever been implemented. In 1990, initial repairs were finally carried out, with more detailed restoration following in 2006 with a budget of 14 million euros. At the start of the restoration the pier was lacking all of its wooden components. MuelleRioTinto1
