According to some historians, the name derives from the Latin "valliceus" (valley), while others attest its origins from the Latin words "vale dium" (Valley of the Gods). Municipality in the province of Verona, located on the edge of the moraine hills that form the Valley of the Mincio, on the borders of Lombardy and Mantua, the town's territory is enriched by the presence of several rivers.
The Valley of the Mincio was inhabited since Prehistoric times, as evidenced by the discovery of artifacts dating back to different eras, some of which are attributable to the Etruscan and the Celt civilizations. The presence of roads and monuments testify that this area was not immune from the Roman colonization. Even though It is assumed that the first permanent settlements were founded after the fall of the Roman Empire, during the period when the territory was subjected to the Lombards. Of great importance for the history of the country was the Venetian domination that began in 1405 and ending after the Napoleonic conquest of the Veneto. Under the influence of the Venetian Republic, the town gradually lost its old military vocation, to become a vibrant commercial and agricultural center.
