Located in San Siro, the former De Montel stables are about to welcome the largest urban thermal park in Italy. With a surface area of 16,000 square meters—6,000 indoors and 10,000 for courtyards and green areas—the spa will offer a space entirely dedicated to wellness. Originally designed in the 1920s by architect Vietti Violi for the De Montel family, the stables were once home to their prized racehorses. After decades of abandonment, they are now at the center of a redevelopment project that blends history, sustainability, and innovation.

The project includes ten thermal pools with a total volume of 800 cubic meters of water, accommodating up to 700 people simultaneously. The facilities will also feature a Russian banya sauna and large relaxation areas. The complex will be powered by low-emission systems and include an innovative rainwater recovery system. The opening is scheduled for March 2025, as confirmed by De Montel - Terme Milano PR office to Domus.
