Corviale is a 1 km long housing complex, the longest in the world housing 8000 persons in Rome, Italy in July, 2007.

ITALY - JULY 01: Corviale' in Rome is the longest single residential building in the world: one kilometer in lenght and housing 8000 persons. The building was commissioned in 1972 to a group of architects directed by Mario Fiorentino to solve the acute lack of housing for working class families. Finished in 1982 the building was based on the idea of social housing according to Le Corbusier, to provide all needed infrastructures of a city within the complex itself, and to encourage social contacts between the occupants. For internal and political reasons many of these originally planned structures were never realized or are, almost 25 years after the first occupants moved in, still unfinished. The occupants discuss missing infrastructures and prejudices from outside which characterize Corviale as a ghetto with high rates of unemployment, criminality and drug abuse in Rome, Italy in July, 2007.
