             city. Water was diverted into the aqueduct by a weir set at an angle across the river.
             Figure 1.32 shows the Roman aqueduct bridge in Segovia with the arches at two
             levels. The aqueduct makes a 90 degree turn in the Plaza of Diax Sanz. This aque-
             duct, built during the second half of the first century or early years of the second
             century, has a maximum height of 28.9 m in the Plaza of Azoguejo. This master-
             piece of engineering consisted of around 20,400 stone blocks that were not held
             together by mortar or cement, making it very unique from an engineering per-
             spective.
