On March 21 and 22, the FAI Spring Days return, the annual event that opens hundreds of normally closed sites across Italy to the public. For one weekend, historic palaces, infrastructure, modern architecture, and industrial sites become accessible thanks to the work of FAI – Fondo Ambiente Italiano – and the collaboration of public institutions and private organizations.
In 2026 the event reaches its 34th edition: 780 venues in more than 400 cities will be open, many of them rarely visited. These include buildings signed by architects such as Gio Ponti, Daniel Libeskind and Carlo Scarpa, along with modernist structures and infrastructures that tell the story of the transformation of the Italian landscape between the 20th century and contemporary times.
The initiative represents the most visible expression of FAI’s work, alongside the year-round opening of 75 properties owned by the foundation. Among the most visited are Piero Portaluppi’s Villa Necchi Campiglio in Milan, which this year also hosted Casa Corea for the Milan-Cortina Olympics, and the Brion Memorial in San Vito d’Altivole, where construction work has just begun on the new Brion Pavilion, designed by Michele De Lucchi's studio. Generally, visits during Fai Days are conducted through a free contribution, but for some places, reservations or a foundation card are required.
In major cities, some extraordinary openings are made possible through collaboration with public institutions and private companies. RAI, for example, will open the studios on Corso Sempione in Milan, designed by Gio Ponti, while in Turin and Rome the broadcaster's historic venues on which Carlo Mollino and Paolo Portoghesi worked, respectively, will be open for visits. Among the special itineraries of the 2026 edition is also an itinerary dedicated to the 800th anniversary of the death of Francis of Assisi, with openings distributed in eight Italian regions, including of course Umbria.
Along with historic buildings and religious complexes, the program includes visits to scientific research centers, factories, theaters and industrial architecture. In this very rich list of places, Domus has selected ten particularly interesting addresses for architecture enthusiasts, from the rationalism of the 1930s to contemporary skyscrapers.
