Imperial Canal of Aragon
The Imperial Canal of Aragon (Canal Imperial de Aragón; Aragoiko Kanal Inperiala) is a 110-kilometre (68 mi) zanja and navigation canal built from 1776 to 1790 between Fontellas (Navarre) and Fuentes de Ebro (Aragón). Its construction was intended to improve the irrigation of the old Acequia Imperial de Aragón, bringing water from the Ebro River to Zaragoza and allowing the irrigation system to be extended in the region.
