Municipality located in the outskirts of Milan, within the lands of the South Agricultural Park. From a geographical point of view, Cusago is part of the greater Milan and features large green areas and cultivated fields.
The discovery of polished stone axe, dating from the III-II millennium B.C., confirms that the area was inhabited since ancient times. The Celts, that already lived in the area, in the II century B.C., were defeated by the Romans, whose presence is confirmed by the names: Cusago, which according to some, is the result of the use of a person's proper name "Cusius", and Monzoro, one of the districts, which derives from the genitive plural of "Montius", "Montiorum".
The settlement Cusago is mentioned for the first time in a document of the Lombards of 902, the "Placito degli Arimanni".
