It is made up by three underground locations in Villa Torlonia, the private residence of Duce in Rome: a cellar – shelter, an underground bunker in the Casino Nobile and an air-raid shelter. The cellar was the first room turned into a shelter in 1940 and employed in the same year. The second bunker was equipped in the central room of the basement of Casino Nobile in 1941 because of the cellar inconveniences and it was used in 1942 and 1943. The fear caused from the persistent Allies bombings pushed Mussolini to order a bunker safer than the other two. A new construction was built, it was armored, dug out 6 meters deep in the underground, under the square in front of the Casino Nobile, with crosswise map, tunnels and heavy roofing in reinforced concrete. The bunker has never been completed or used by Mussolini, because he was overthrown and arrested on 25th July 1943.
The locations come to light after the restauration works. The exhibition itinerary includes also some furnishings connected to the function of the places, so that they can be better understood.
