Treviglio

Treviglio lies on the plain between Milan and Bergamo, in the district known as the Gera d'Adda. Its name recalls the union of three older settlements, Cusarola, Pisgnano and Portoli. The inhabitants enclosed their town with walls, and a document of 964 records the settlement by name.

From 1395 Treviglio was generally a separate territory of the Duchy of Milan, though Venice occupied it on several occasions in the fifteenth century, including the years 1431–33 and 1448–53. The last Venetian occupation ended in 1509, when the town was sacked and burned in the course of the war. French forces under Louis XII then crossed the Adda and defeated the Venetians at the battle of Agnadello. Treviglio and the Gera d'Adda remained closely linked to Milan thereafter.
