Cinecittà opened in 1937 as a state-run film city, built in fifteen months on farmland outside Rome, and the motto over the gate said that cinema is the strongest weapon. It is a walled campus of low white buildings and sound stages. The largest of them is Teatro 5, nearly three thousand square metres under a fourteen-metre roof, with a tank of water sunk into the floor, and it is still the biggest sound stage in Europe. Fellini worked in it for thirty years, building the Rome of his films inside the studio rather than filming the real city outside.
Between 1944 and 1950 no films were made here at all. The Allied authorities requisitioned the studios and turned them into a camp for people who had lost their homes. Italians bombed out of the cities, families of colonists returned from Libya, refugees from Trieste and Dalmatia, Jews coming back from the camps. They lived in the sound stages, divided from each other by pieces of film scenery. When the camp closed, American productions arrived to use the cheap crews and the big stages, and the studios spent a decade making Roman epics ten kilometres from Rome.
