Arroyo Salado Roman Bridge

It was built using a type of local sandstone called "molinaza" and a building technique known as Opus Quadratum. Most researchers date it to the 1st century, in the time of Augustus. Its most significant features are an asymmetric structure consisting of a central arch flanked by two smaller side arches; and a third on the right-hand side that can be seen when looking upstream. The ashlar padding also give it almost sculptural plasticity. The are triangular breakwaters on the upstream side that channel the waters towards the arches.

It was in use from the time it was built until the middle of the 20th century, and it played a leading role during the Modern Age as a result of the economic activity motivated by Trade with the Indies.
