Milan, restoration of the Sala delle Asse at the Castello Sforzesco approved


In Milan, the city council has approved the restoration of the Sala delle Asse at Castello Sforzesco, with walls painted by Leonardo da Vinci. Construction will start in early 2025.

In Milan, the city council has approved the technical and economic feasibility project for the restoration of the Sala delle Asse at Castello Sforzesco. The work site, which will begin in early 2025, aims to recover and safeguard the precious wall paintings by Leonardo da Vinci.

The project, drawn up by Michela Palazzo for the Superintendency in collaboration with the offices of the Cultural Buildings Area and the Culture Department, is the result of years of research and surveys on the Hall’s 15th-century decorations. The paintings have been deteriorated by time and previous restoration work, and restorers will be tasked with restoring integrity to the work, ensuring its preservation and enjoyment for future generations.



The value of the intervention amounts to 1 million 625 thousand euros, financed partly by the Administration’s own resources and partly by Fondazione Cariplo. After the executive design phase and the awarding of the tender, the construction site is expected to last more than a year, with a scheduled start in 2025.

The restoration of the Sala delle Asse represents an intervention of great importance for Milan’s cultural heritage. The hall, famous for its wall decorations attributed to Leonardo da Vinci, is one of the artistic gems of the Castello Sforzesco. The recovery of these wall paintings will not only enhance one of the masterpieces of the Italian Renaissance, but will also help strengthen the city’s cultural offerings, attracting tourists and scholars from all over the world. With construction scheduled to begin in 2025, citizens and visitors to Milan will thus be able to witness the rebirth of one of the city’s most emblematic sites.

“This is a long-awaited project,” comments Councillor for Financial, Economic and Patrimonial Resources Emmanuel Conte, “for a unicum in the history of art, which will proceed in parallel with other major cultural construction sites such as the Beic and the Museum of the Twentieth Century, in the spirit of a city capable of enhancing the treasures of its past while opening to the future by creating new places of beauty, culture and art.”

“We are happy that the last phase of restoration of this extraordinary Leonardesque testimony at the Castello Sforzesco has reached its final stage,” says Councilor Tommaso Sacchi. “The Sala delle Asse will therefore be able to be permanently reopened, after years of studies, essays and investigations on the walls and ceiling, and admired by all the citizens and visitors who will come to Milan for the 2026 Olympics.”
