The Bacchiglione (Latin Medoacus minor) is a river that flows through northern Italy. It starts in the Alps and empties into the Gulf of Venice, on the Adriatic Sea, near Chioggia. It flows past a number of cities, including the Vicenza and Padua, and acted for many centuries as a significant waterway up to Vicenza, after which it ceases to be navigable. Recently, the Bacchiglione has gained a reputation for containing water dangerous to drink.
