The association Senza Tempo formed in 2011 aims to recreate historical atmospheres spanning different eras. The WOW effect on the public in recreating indoor and outdoor environments and situations has been well achieved over the years by organizing historical events on its own account or by being part of the direction of major events such as the Grands Jeux Romains in Nimes.

As of March 15, 2025, the Senza Tempo team will be in charge of the opening of the Quintino Sella Antiaircraft Shelter in the heart of the city.

A journey back in time to the Spice of the 1940s: the museum tour of the Quintino Sella Aircraft Shelter combines virtual reality, video mapping and an interactive avatar of the Anti-Aircraft Protection (U.N.P.A.) to explore collective memory. Temporary exhibitions with historical artifacts and educational workshops (active from September 2025) complete the experience, creating a bridge between past and future to reflect on peace.
