The Vizcaya Hanging Bridge also represents the high point of a long cultural tradition linked to the preparation and use of iron from Vizcaya. Iron has been intensively exploited since Roman times and throughout history has made a significant contribution to the growth of all of the European Atlantic countries and played a decisive role in the development of agriculture, mining and industry in Spanish colonial America.
The Vizcaya Hanging Bridge is situated next to one of Europe’s most important historical iron deposits, from which over 50 million cubic metres of mineral have been extracted and which was at its highest output at the time the Bridge was being built. Since the 13th century iron from these mines was exported in abundance to the markets of France, England and Holland and in the 16th century over 300 hydraulic iron works in the Basque Country distributed their metal products pretty much without competition not only in Spain and European markets, but to all of the new Spanish colonies in the American continent.
