Gulf of Venice
At the northern end of the Adriatic, the Gulf of Venice reaches from the Po delta to the tip of Istria. In antiquity it formed the southern end of the Amber Road. The rise of Venice gave the gulf a name once applied to the entire Adriatic, a measure of the republic's maritime prominence. In the War of Chioggia, Genoese forces carried the rivalry between the two maritime republics into Venice's own lagoon. They seized Chioggia and large parts of the lagoon, but the Venetians recovered them before the Treaty of Turin ended the war in 1381. Both sides suffered heavy economic losses in the struggle.
