Already pretty much at the end/beginning of the railway line, here it is even asphalted, before/later not anymore, but always easy to ride.

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.
