Passage: To reach the old city, the water is conveyed by its aqueduct bridge. At Plaza de Díaz Sanz (Díaz Sanz Plaza), the structure makes an abrupt turn and heads toward Plaza Azoguejo (Azoguejo Plaza). It is there the monument begins to display its full splendor. At its tallest, the aqueduct reaches a height of 28.5 m (93 ft 6 in), including nearly 6 m (19 ft 8 in) of foundation. There are both single and double arches supported by pillars. From the point the aqueduct enters the city until it reaches Plaza de Díaz Sanz, it includes 75 single arches and 44 double arches (or 88 arches when counted individually), followed by four single arches, totalling 167 arches in all.
