One of the most publicized civil constructions in Bizkaia. Its charm has always been highly appreciated by painters, photographers and travelers. The footbridge joins the two banks of the Cadagua River where the neighborhoods of El Cristo and San Lorenzo are located, respectively, a place that occupied a modest Jewish aljama until 1492. It has a cobbled pavement.
