Probably built during the Flavio period, between
the late 1st and early 2nd centuries, when Vespasiano and Trajano
were emperors, in order to bring water from the river Acebeda
to the city.
This magnificent work of engineering, that is still in excellent condition, begins near the Granja Palace with simple arches and carries the water to a tank known as "el Caserón". An ashlar canal then transports the water to a second tower and once it reaches Diaz Sanz square, row upon row of arches tower high above the ground. Its 20,400 stone blocks are neither cemented nor stuck together by any substance, and they remain as a solid perfect block up until this day.
The maximum height of the structure is on the Azoguejo Square at 28.10 m and a total of 166 arches.
