Port of Augusta, Commercial port in Augusta, Italy

The Port of Augusta is a large commercial harbor on the eastern coast of Sicily, divided into three sections: Porto Xifonio, Porto Megarese, and Seno del Priolo. It handles mostly oil and petrochemical cargo, making it one of the most active ports in the Mediterranean.

The natural inlet was used as a harbour since ancient times; Frederick II of Swabia had coastal fortifications built there in the 13th century. In the 1910s the Regia Marina used it during the Italo-Turkish War, and between 1917 and 1920 an airship hangar was built, converted into a seaplane station in 1925. The British Navy occupied it from 1943 to 1946, and in 1949 Angelo Moratti's Rasiom refinery began large-scale industrial use.

Augusta's name comes from Emperor Frederick II, who called the bay "Augusta" in Latin, meaning majestic. The port's three sections keep older names: Porto Xifonio and Porto Megarese recall the Greek and Roman past, while Seno del Priolo refers to the Priolo refining plants facing it. The port hosts the Capitaneria di Porto di Augusta.

Most of the port is closed to the public since it is an active industrial and shipping zone, but the waterfront road offers open views of the docks and vessels. Walking along the coast on the Augusta side gives the clearest perspective of the whole port area.

Between 1917 and 1925 the harbor hosted a concrete hangar built for airships, which was later converted into a seaplane base. This largely forgotten structure shows how the port served both air and sea military operations during the same period.
