Outside Udine Gate you will find the imposing structure of the Venetian Aqueduct. Although its construction dates back to the origins of the fortress, it was restored several times: in 1665, i.e., under the superintendency of Alvise Molin it was rebuilt completely with stones from Medea, but only in 1771 it assumed its present shape. The aqueduct was used to conduct the water of the Palma Canal inside the fortress for civic use. The central plaque, created in 1751 by the citizen of Palmanova Carlo Pico, represents a lion’s skin between two female allegorical figures: Igea and Sorgente. It laso contains a laudatory epigrahp on the superintendent Pisani; in 2013 it was completely restored by the superintendency.
