From stone walls to street art
Milan is not just the financial and fashion capital: its walls tell a visual story spanning over five hundred years. From mottoes of faith carved into stone and 19th-century satires to modern graffiti and sticker art.
This mini-guide is an invitation to look up between commitments, following the evolution of Milanese "mural communication" on a journey through the centuries.
15th and 16th centuries: messages carved in stone
Before paper and spray paint, walls communicated faith, power, and commercial rules through engravings and mottoes sculpted to last for centuries.

The "HUMILITAS" Portal
Former Archiepiscopal Seminary (now Portrait Milano)
On the building's facade stands an imposing Baroque portal topped by the relief inscription HUMILITAS, the motto of the Borromeo family. It creates a unique visual contrast between the monumentality of the stone and a message of modesty.

The A.U.F. Marks and towpath scars
On the stones enclosing the Darsena and the Naviglio Grande, you can spot the A.U.F. (Ad Usum Fabricae) marks, used to exempt marble intended for the Duomo from taxes, along with the grooves worn by the chains used to tow barges against the current.
17th and 18th centuries: stone edicts and public order
As civil and religious institutions consolidated, stone became the official medium through which power established rules of co-existence and urban decorum.

The 1609 "Anti-Noise" plaque
A stone tablet embedded beneath the city center's porticoes that strictly prohibited games, shouting, and noise. It proves that public order signage and space management are ancient inventions.
19th century: Risorgimento satire and political protest
Between the Austrian occupation and the Unification of Italy, walls became the people's tool for political satire and expressing dissent safe from censorship.

The statue of Sciur Carera
A Roman-era sculpture located under the porticoes of the city center. In the 19th century, it became Milan's "Pasquino": at night, citizens attached anonymous notes with satirical poems and mockery directed at the Austrian government.
20th century: mural advertising, popular memory, and the first murals
With the industrial boom, Milan became the capital of graphic design. Later, the blank building facades in working-class neighborhoods transformed into canvases preserving community memory and identity.

Vintage signs and nural advertising ("Ghost Signs")
Great illustrators like Marcello Dudovich and Leonetto Cappiello designed the first posters and painted advertisements. Along the buildings, you can still catch glimpses of commercial ads and hand-painted shop signs made with lime directly on the bricks.

The Ortica open-air museum (OR.ME District)
The building facades of this eastern neighborhood were entirely covered with majestic murals created by the Orticanoodles collective, tracing the 20th century through the faces of partisans, musicians, and workers.

The walls of poetry
In the hidden heart of the Navigli district, the walls adjacent to the house-museum of poet Alda Merini feature painted quotes, portraits, and verses that blend seamlessly into the historic casa di ringhiera courtyard buildings.

The dialogue between graffiti and urban history
During the late 20th century, key transit hubs and landmark locations hosted authorized urban art pieces and graffiti that engage in a dialogue with history.
- Garibaldi Station (Underpass)
- Church of San Cristoforo sul Naviglio
- Colonne and Basilica di San Lorenzo
21st century: widespread street art and the urban "treasure hunt"
Today, mural communication is fast, witty, and spread across urban fixtures, turning everyday walks into a treasure hunt for artistic details.

Merioone's "Fishes Invasion"
The colorful, irreverent fish posters and sticker art by the Roman street artist pop up on the backs of street signs and electrical boxes, accompanied by the warning "Don't Sleep!".

Hidden installations, mosaics, and modified signs
By looking closely, you can spot Invader's 8-bit mini-mosaics, C215's stencil works on mailboxes, and Clet's reimagined street signs.
