The town's name, for some historians, derives from the Latin word "brigantinum" (brigantino, a small ship used by pirates that, according to legend, shored on the banks of the River Po). A second theory attests its foundation to a tribe of Celtic origins, known as Brigantii, while a third school of thought gives it a Greek meaning: flowered swamp.
Municipality in the province of Rovigo, located on the left bank of the Po, in the western part of the Polesine region, the territory of Bergantino is on the border with Lombardy.
The discovery of the remains of prehistoric settlements evidence that the area was inhabited and the houses were built on stilts. It became a Gaul outpost and was colonized by the Romans in the II century B.C. When the Empire fell, the area found in the ecclesiastical power an important point of reference. The town, for several years, submitted the domain of Ferrara, contended by Verona and then destroyed by the Venetians in 1482. It became a French possession in the late XVIII century and after a short period of Austrian domain, the area shared with the rest of the Veneto region, the most recent history.
