Corviale is one of the housing projects built on the outskirts of Rome in the 1970's as part of the 1964 regional plan to alleviate crowding in the older central city. It is well-known as the longest single residential building in Europe: an 11-story high slab of apartments nearly 1 km in length. Conceived as an independent community for about 8000 people including other facilities such as schools, shopping, recreation facilities and even a church, the building was based on the idea of social housing 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 20 years after the first occupants moved in, still unfinished. The area suffers from the lack of an adequate metropolitan infrastructure and it remains isolated from the greater city of which it was intended to be a part.
