The Aqueduct of Segovia

The Aqueduct of Segovia (or more precisely, the aqueduct bridge) is a Roman aqueduct in Segovia, Spain. With the Pont du Gard in France, it is one of the best-preserved elevated Roman aqueducts. It is the foremost symbol of Segovia, as evidenced by its presence on the city's coat of arms. © istock/ SeanPavonePhoto
