M'illumino di Meno (Rome)

A symbolic day for the planet

M'illumino di Meno is the National Day for Energy Saving and Sustainable Lifestyles, conceived in 2005 by the Caterpillar radio show on Rai Radio2. Every year, around February 16th, cities, schools, companies, associations, and administrations across Italy switch off the lights in squares, buildings, and iconic monuments for a few minutes to remind everyone how precious every act of energy sobriety is. From a simple radio invitation, the initiative has grown over the years to become the country's most widely supported environmental campaign.

Rome turns off its facades

Participation in the capital is particularly evocative: the Directorate of State Museums of the City of Rome involves some of the city's most beloved landmarks, which remain in the dark for half an hour, usually from 7:00 PM to 7:30 PM. Key participants in the blackout include the Pantheon, with its portico and side facades, and the cylinder of Castel Sant'Angelo, along with the Boncompagni Ludovisi Decorative Art Museum, the Hendrik Christian Andersen Museum, and the National Museum of Musical Instruments. Palazzo Valentini, the seat of the Metropolitan City of Rome Capital, also joins the initiative by switching off its lights. Seeing the Pantheon shrouded in darkness, illuminated only by the moon and streetlamps of the city center, is a rare and powerful experience.

Much more than just a blackout

M'illumino di Meno goes beyond the symbolic gesture. Around February 16th, municipalities and citizens organize moonlight walks, candlelight dinners, recycling workshops, environmental education meetings, and initiatives dedicated to sustainable mobility, the use of renewable energy, and waste reduction. Each edition revolves around a theme: in 2026, the focus is on the role of science and research in the fight against the climate crisis.

A commitment that unites Italy

From the Colosseum to the Uffizi, from small villages to large cities, thousands of locations participate in the day every year. The Sustainable Municipalities Network works alongside Caterpillar to involve local administrations, rewarding those that stand out for their originality and ability to raise citizen awareness. In Rome, the institutional and cultural heart of the country, the initiative takes on a special value: the capital, with its world-renowned monuments, becomes for one evening the symbol of an Italy that chooses sobriety and responsibility toward the environment.

A gesture within everyone's reach

The message of M'illumino di Meno is simple: turning off a light won't solve the energy crisis on its own, but it serves as a reminder that every daily behavior counts. Participating in Rome means joining a collective ritual that, from the Pantheon to citizens' homes, transforms a small individual gesture into a major shared signal.
