 Arcore, in the Middle Ages, is under the control of the "Pieve of Vimercate", and is historically documented the presence of two monasteries, la Casa delle Umiliate in Sant'Apollinare and the Benedictine monastery of Saint Martin of Tours.By the 16th century, several noble lombard families (Casati, Durini, Giulini, Vismara, D'Adda, Barbò) begin to build many important villas usually surrounded by park, the "ville di delizia", including the Villa Borromeo-d'Adda, the Villa la Cazzola and the Villa San Martino (the current residence of Silvio Berlusconi).After the Italian unification (1861), through the construction of the 2 Arcore's railway stations (the first in front at Villa Borromeo-D'Adda, and the second - of a different railway line - located in "Ca' Bianca-Buttafava") and the establishment of numerous industries (like Gilera), the city has gradually expanded up to become, today, one of the most active and largest city in Brianza.
