Tunnels used to transport water in the Aguas Livres aqueduct, Lisbon. 05 December 2021. The Águas Livres aqueduct or "The Free Waters aqueduct" is a structure designed by King Juan V for the distribution of drinking water in the city of Lisbon. Although it was completed in the 19th century, by 1748 it was supplying water to the city.The main canal measures 19 km, although the total length, including the secondary canals, is 58 km. The best known part is the 35 arches over the valley, the highest of which is 65 meters high. The public road over the aqueduct has been closed since 1853, partly because of the crimes perpetrated by Diogo Alves, a criminal who threw his victims from the top of the arches. Today it is possible to take a guided walk over the arches. It is also possible, occasionally, to visit the Water Museum reserve.
