 One of the first known names of the town is the Latin name of Guardiae Longobardorum, which later became Guardiae de Lombardis (AD 1100-1300).The name was then changed to Guardialombarda (AD 1400-1600), then Guardia Lombarda (AD 1600-1800), then Guardia dei Lombardi (for the first half of 1900), and finally Guardia Lombardi.There is a hypothesis that the founding of Guardia Lombardi occurred much earlier than many documents indicate.
