Parabiago (Milanese: ; ) is a town located in the north-western part of the Metropolitan City of Milan, Lombardy, northern Italy. The town is crossed by the road to Sempione (S.S.33) and MilanGallarate Railway; nearby flow the Olona river and the Canale Villoresi. History Ancient history and Middle Ages Starting from the first Celtic-insubrian settlement (4th century BC), it developed during the Roman Empire rule, as documented by various archaeological discoveries of little objects, including the Parabiago Plate, a silver plate probably used to cover an ashes urn. In the Early Middle Ages, Parabiago was the centre of a parish (pieve) and of an autonomous county, named Comitatus Parabiagi and sometimes Burgaria, governed by the Sanbonifacio family, of Frankish descent, coming from Verona; in the 7th century, it received by the Lombard queen Theodelinda the permission for a little artificial stream, named Riale or Röngia, which took water from the Olona river and travelled through the village: that stream lasted until the 1928, when it was definitively stilted up. The Truce of Parabiago (2829 August 1257) led to the Pace di Sant'Ambrogio (Saint Ambrose's Peace), so called because it was signed in the homonymous Basilica in Milan). It put an end to the risk of a civil war between nobles and people in the free commune of Milan. On 21 February 1339, it was the location of the Battle of Parabiago between Lodrisio Visconti and Luchino Visconti with his nephew Azzone, for the dominion over the Duchy of Milan; the battle was won by the Milanese regular army; according to tradition, this happened thanks to the miraculous apparition of Saint Ambrose. During this time, the Crivelli family inherited from the Sanbonifacio family the County of Parabiago, perhaps still corresponding with the Burgaria County. In the following centuries Parabiago had a slow decline; it suffered two pillages, in 1449 by Francesco Sforza and in 1527 by Bourbons of Spain, as well as two epidemics (1529 and 1540). Modern Age During Spanish rule in the Duchy of Milan, the Marquis Camillo Castelli bought the Fief of Parabiago for 8800 lire (26 September 1658); the family extinguished in 1783, with the death of Cardinal Giuseppe Castelli. Parabiago developed in the 18th century, during the Austrian rule. Between the 19th and 20th centuries the Industrial Revolution reached Parabiago. The most active industrialists were Felice Gajo, who established the Unione Manifatture di Parabiago (United Manufacturing
