 According to historians, the name ‘Castrum Valterii’ is linked to Longobard ‘Gualtiero’, who was sent by King Agilulf in 602 to conquer Mantua.In the 2nd century BC, with Roman colonisation, the territory was split up.The signs of centuriation still are evident not far from Brescello (Brixellum), a village around which the settlement of Gualtieri revolved until the Lombard Age.
