The bridge was built in the 11th century and served as an important crossing point on the old road to Castile. It crosses the Cadagua River and is one of the city's landmarks. The bridge consists of three arches and has a Gothic tower added in the 15th century. This tower was formerly used to collect tolls.

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.

The road that goes near the town of Partearroyo, you can see the views of the Ordunte Reservoir and its extension along the foot of the Montes de Ordunte. In the area there is a series of pretty villages typical of the area.
