The Aqueduct of Segovia (or more precisely, the aqueduct bridge) is a Roman aqueduct and one of the most significant and best-preserved ancient monuments left on the Iberian Peninsula. It is the foremost symbol of Segovia, as evidenced by its presence on the city’s coat of arms.

As the aqueduct lacks a legible inscription (one was apparently located in the structure’s attic, or top portion), the date of construction cannot be definitively determined. Researchers have placed it between the second half of the 1st Century CE and the early years of the 2nd Century—during the reign of either Emperor Vespasian or Nerva. The beginnings of Segovia itself are likewise not definitively known. Vacceos are known to have populated the area before the Romans conquered the city. Roman troops sent to control the area, which fell within the jurisdiction of the Roman provincial court (Latin conventus iuridici, Spanish convento jurídico) located in Clunia, stayed behind to settle there.

The aqueduct transports waters from Fuente Fría river, situated in the nearby mountains some 17 kilometers (10.6 miles) from the city in a region known as La Acebeda. It runs another 15 kilometers (9.3 miles) before arriving in the city. The water is first gathered in a tank known as El Caserón (or Big House), and is then led through a channel to a second tower known as the Casa de Aguas (or Waterhouse). There it is naturally decanted and sand settles out before the water continues its route. Next the water travels 728 meters (0.45 miles) on a one-percent grade until it is high upon the Postigo, a rocky outcropping on which the old city center, the Segovia Alcázar, was built. Then, at Plaza de Díaz Sanz (Díaz Sanz Square), the structure makes an abrupt turn and heads toward Plaza Azoguejo (Azoguejo Square). It is there the monument begins to display its full splendor. At its tallest, the aqueduct reaches a height of 28.5 meters (93.5 ft), including nearly 6 meters (19.7 ft) of foundation. There ar…
