Amid the noise of modern cities, where faces look tired and hearts are preoccupied, the Italian city of Milan surprises us with a law like no other: in public spaces, you are required to smile—not just as good behavior, but as a legal obligation.

Yes, what you’re reading is true. While laws are typically studied as principles for organizing life, Milan has an old law that reflects a more poetic view of civil life, requiring citizens to maintain a cheerful appearance and avoid frowning in the streets.

This amusing law dates back to another era—specifically the 19th century—when Italian authorities sought to lift public morale and encourage social discipline through unconventional regulations. Since public mood is a subtle yet crucial element of social stability, authorities at the time believed that smiling in public was essential for the well-being of the community.

This was more than just a law; it was seen as a positive reflection of the Italian spirit, which has long blended love, art, and joy.

Of course, the law was realistic in some respects—it exempted moments of deep sorrow such as funerals or hospital visits, giving people a natural space to express pain and grief.

Although this law is no longer enforced today, its symbolism lives on. Modern science confirms what Milan once intuitively understood: a smile isn’t just a facial movement, but a psychological and social act that spreads positive energy and uplifts others emotionally.

So, that old Milanese law wasn’t shallow or whimsical—it was an early attempt to understand how outward behaviors deeply affect inner well-being.

Beyond the city’s charm of fashion and high-end design, Milan’s residents still enjoy sharing this story with tourists—blending humor with wisdom—and showing how a simple law can carry a deep message about the art of living and the shared responsibility of spreading hope, not gloom.
