Baggio (Lombard: Bagg [ˈbatʃ]) is a district (quartiere) of Milan, Italy, part of the Zone 7 administrative division of the city. Before being annexed to Milan in 1923, it was an autonomous comune. The origin of name Baggio is disputed. Some scholars suggest that it might be from a Roman military tower called Badalocum (in Latin, "watch the place"); others have it derive from a toponymy Badia Aggeris, possibly referring to an abbey, which over time was contracted into Badagio and later distorted into Badaglo, then Badaxio, and eventually Baggio.
