The earliest evidence of human life in the area of Gambolò, found on the right bank of the river Terdoppio, dates from the recent Mesolithic era (5500-4500 B.C.). A number of villages, of which the many cemeteries serve as evidence, sprang up in the second half of the 3rd century B.C.. The village was first mentioned in 999 in a document specifying that a certain Ademarus de Gambolate had to compensate the bishop of Vercelli, Leone, for the incurred damages. The castle was first mentioned a century later, in 1099.
