city, Lombardia (Lombardy) regione, northern Italy. It lies along the Lambro River, just northeast of Milan. The ancient Modicia, it was a village until the 6th century AD, when the Lombard queen Theodelinda established a residence and a monastery there. During the period of the communes, Monza was sometimes independent, sometimes subject to Milan. The Visconti family built a castle there in 1325. The town withstood many sieges and was repeatedly plundered, notably by the troops of Charles V. King Umberto I of Italy was assassinated at Monza on July 29, 1900; an expiatory chapel was dedicated in 1910.
