Archaeological excavations haven proven the presence of humans in the area since prehistoric times, in the area of Cisano. There also traces of ancient Romans, though the modern settlement dates to the early Middle Ages, when Berengar of Italy (983) had a castle built here. In that period the area was under the suzerainty of the Bobbio Abbey. In the 12th century Bardolino is mentioned as a free commune, and later was under the Scaliger of Verona, who enlarged the fortifications to encompass the whole village. After their fall, it became part of the Republic of Venice which had a marine base here. In 1526 it was sacked by the Landsknechts. Under the Lombardy-Venetia, it was an Austrian administrative center: in 1848 it revolted against them in the wake of the first Piedmontese victories in the First Italian War of Independence. However, later the Austrians retaliated with ravages and shootings. It was annexed to the newly formed Kingdom of Italy in 1866.
