Archaeological excavations in the Mincio valley include a Bronze Age settlement, some tombs dating to the Iron Age and some findings associated with the Etruscan civilization. During the work of river channelling in 1955–56 at Isolone della Prevaldesca a pile-dwelling settlement came to light which led to the collection of 16,000 finds; some tombs and other finds dating to the Iron Age were found in Borghetto and some finds associated with the Etruscan civilization. A large Celtic necropolis, found in 1984 still partly buried under the current town, would prove the presence of that people from the 4th century BCE and the 1st century CE. In the necropolis, found in 1984, were also discovered finds and marble funeral monuments from Roman times, as well as traces of traffic connections linking the ford on the river to consular roads. The creation of the villages of Valeggio and Borghetto dates to the Lombard rule in Northern Italy because their names derive from 'flat place' and 'fortified settlement' respectively. The monastery of Santa Maria was founded here, on the banks of the Mincio, in the 12th century; later it was a priory of the Knights Templar. The large medieval fortifications which characterize Valeggio were built between the 13th and the 14th centuries. In 1405 Valeggio became part of the Republic of Venice, and subsequently lost its strategic role, becoming an agricultural center and a silkworms trading market. After the fall of the Republic of Venice in 1797, Valeggio was included in the Cisalpine Republic. Later it was part of the Italian Republic and then of the Kingdom of Italy. With Napoleon’s fall, the Congress of Vienna established the entrance of Valeggio in the Kingdom of Lombardy-Venetia, an Austrian Empire dependence. During the Italian Unification, the town was a protagonist of the battles of the First, Second and Third Italian War of Independence, which led to the creation of the newly unified Kingdom of Italy. In the Second World War the Monte Borghetto was bombarded ; on 14 February 1944, an American aircraft B-17 fell during a dogfight in the locality of Vanoni-Remelli, causing the death of both a civilian - who was working in the fields near a water canal - and pilot Harold Arthur Bond Jr.
