Milan by metro: reading the city through its five lines
Milan’s metro is more than transport. Colours, signage, architecture and interchanges build a mental map that helps first-time visitors understand the city quickly.
The five lines represent different phases of urban development, from M1 in 1964 to M4 linking Linate with the centre and western districts.
A network of colours and directions
The lines are M1 Red, M2 Green, M3 Yellow, M4 Blue and M5 Lilac.
To choose the correct platform, read the direction, shown by the name of the terminus.
- identify the line and colour;
- check the terminus for your direction;
- count stops and changes;
- choose the exit closest to the destination.
The birth of M1 and the design system
Milan’s first metro line opened in 1964. Franco Albini, Franca Helg, Antonio Piva and graphic designer Bob Noorda developed the interiors and signage.
Coloured bands, legible lettering, repeated station names and the “M” symbol created an internationally influential wayfinding system.
The metro fittings and signage received the Compasso d’Oro in 1964, linking mobility with Milanese design culture.
Looking at M1 while using it reveals a gallery of everyday design: red bands, handrails, lamps, finishes and station names form a coherent environment that commuters often cross too quickly to notice.
M1 Red: Rho Fiera, the centre and shopping axis
M1 is the essential line for Fiera Milano. Rho Fieramilano connects directly with Lotto, Cadorna, Cordusio, Duomo, San Babila and Porta Venezia.
Use Lotto for M5 and CityLife, Cadorna for Castello and Brera, Duomo for the historic centre, San Babila for the Fashion District and Porta Venezia or Lima for Corso Buenos Aires.
A hotel on M1 can greatly reduce changes during a fair-related stay.
M2 Green: stations, Brera, Porta Genova and Navigli
M2 serves Centrale, Garibaldi, Cadorna and Porta Genova.
Lanza is useful for Brera and Parco Sempione; Sant’Ambrogio for the basilica and university area; Porta Genova for Navigli, Darsena and Tortona.
The line branches east and south, so check the train destination carefully.
M3 Yellow: Centrale, Duomo and the north–south axis
M3 links Milano Centrale with Repubblica, Montenapoleone, Duomo, Crocetta, Porta Romana and Rogoredo.
Montenapoleone serves the Fashion District; Rogoredo is a major railway interchange.
At Duomo, M3 meets M1, connecting the Centrale axis with Rho Fiera and San Babila.
M4 Blue: Linate, centre and western Milan
M4 links Linate Airport with San Babila, central Milan and San Cristoforo.
San Babila connects with M1 and Sant’Ambrogio with M2, simplifying journeys between airport, fair and central districts.
Visitors can enter the urban network without relying on road traffic.
M5 Lilac: Garibaldi, CityLife and San Siro
M5 connects Bignami, Isola, Garibaldi, Monumentale, Lotto, Tre Torri and San Siro.
Tre Torri serves CityLife; Isola and Garibaldi serve BAM and Porta Nuova.
Lotto is the key M1–M5 interchange from Rho Fiera to CityLife or San Siro.
The most useful interchanges for fair visitors
- Lotto M1–M5 for CityLife and San Siro;
- Cadorna M1–M2 for the station, Brera and Navigli;
- Duomo M1–M3 for Centrale and the north–south axis;
- San Babila M1–M4 for Linate;Garibaldi M2–M5 for Porta Nuova, Isola and trains.
A well-chosen interchange matters more than map distance. Identify the station and the next terminus before leaving.
Some interchange corridors require several minutes of walking.
Tickets, contactless payment and station exits
ATM services can be used with tickets, passes and, where enabled, contactless cards or devices. Use the same payment method throughout and follow entry and exit prompts.
The fare system extends beyond central Milan. Rho Fieramilano requires a ticket valid for the full zone journey.
Large stations have several exits. Choosing the right one saves time at street level.
Accessibility and service changes
ATM publishes information on lifts, escalators, accessibility and planned service changes.
Travellers with reduced mobility, heavy luggage or pushchairs should check the departure, interchange and arrival stations in advance.
The ATM maps; real journeys also require live updates and the final walking route.
The Milanese insider
On the M1, look at the details too
On the Red Line, for once do not just look at the station name. Notice the typeface, colored bands, handrails, lighting and furnishings: the work of Franco Albini, Franca Helg and Bob Noorda turned the metro into a landmark example of Milanese design applied to everyday life.
