[1] At the end of the 19th century, the development Rogoredo benefited from its connections to Milan, through the Porta Romana city gate and by the Milano-Lodi tramway.

At the time, the settlement went through a fast industrialization process, most notably with the establishment of the Acciaierie Redaelli steel mill and the explosive material factory Società Italiana Prodotti Esplosivi, later absorbed by Montedison.

Public transports to Rogoredo were likewise enhanced through the century, with the old tramway being gradually replaced by trolleybuses and then buses, and lastly complemented by the Milan Metro subway (Line 3).

The subway increased activity in the area, especially as the Rogoredo station absorbed much of the commuting between Milan and the southern part of the Province (Pavia, Piacenza, Lodi, Voghera).

This area, which includes the headquarters of Sky Italia, will thus cease to be part of Rogoredo and become a district on its own, named Milano Santa Giulia.
