Visits to Mussolini's Bunker at Villa Torlonia return - Last hour. Six meters below the now flowery lawns of the park - four meters of reinforced concrete above your head.

The floor shakes under your feet and the sirens sound while the noise of the bombs resonates between the curved walls like those of a submarine. Built for Mussolini, who took up residence on the estate along Via Nomentana in 1929, they ended up being used instead by Roman citizens to defend themselves from bombings.
