The historical set of the Roman Bridge of Cordoba, in Spain, includes not only the viaduct, but also part of the monument, the Gateway to the Bridge and the “Calahorra” Tower. The Gateway to the Bridge was built by the architect Hernán Ruiz III in 1572, by order of Felipe II. The defensive tower known as the “Calahorra” Tower, built during the centuries of Muslim occupation of the city, is located at one end of the Roman Bridge.
The Romans, being the first to build stone bridges, made them so solid and strong that there is no doubt about their resistance to the onslaught of time. It is said that it was an important means of entry to the city from the south of the Iberian Peninsula because it is the only point to cross the river without using any type of boat.
