San Carlo, Residential district in Lombardy, Italy.

San Carlo is a residential district in Lombardy featuring apartment buildings set among green spaces and dotted with small local shops and services. The neighborhood's layout follows a suburban pattern with tree-lined streets and modest commercial areas interspersed throughout the housing blocks.

The district's landmark is the former Ospedale Umberto I at via Solferino 16, built between 1893 and 1896 as one- to three-storey pavilions separated by green areas and named after King Umberto I in an anticlerical, monarchical era. In the early 2000s its departments moved to the new San Gerardo hospital in the Cazzaniga district; since 2010 only a small part is used as a hospital, while the rest home, church and some municipal offices remain.

Piazza Indipendenza is the district's main gathering point, lined with shops that residents use daily. The neighbourhood is named after San Carlo, the saint to whom the chapel in the former Umberto I hospital complex on via Solferino is dedicated; that chapel is still standing among the pavilions.

The neighborhood connects to Milan's transportation network through regional buses and roads, allowing easy commuting and access for visitors. Local shops and services are distributed throughout the area, making it straightforward to find everyday necessities without traveling far.

The former Umberto I hospital complex, built between 1893 and 1896 on via Solferino, consists of one- to three-storey pavilions separated by green areas; since 2010 only a small part still serves as a hospital, while the rest is being reassigned to university courses of Milano Bicocca.
