In the Middle Ages it was a stronghold of Verona, which built here a castle in 1151. In 1308 it was a fief of the Scaliger, who were succeeded by the Visconti in 1381 and the Gonzaga in 1391. Ostiglia's history was subsequently connected with that of Mantua, losing its strategical importance; its castle was demolished by order of emperor Charles VI in 1717.
