It was probably built in the time of the Flavians, between the second half of the 1st century and the beginning of the 2nd century, when Vespasian and Trajan were emperors, in order to transport water from the Acebeda River to the city. This impressive work of engineering, in excellent condition, starts near the Palacio de la Granja with simple arches that lead the water to the cistern known as the Caserón. Subsequently, a channel of ashlars transports it to a second tower and, upon reaching the Plaza de Díaz Sanz, two monumental rows of superimposed arches begin to form.
