After the first World War, Rome used to have a great period of urban redevelopment, compared in a way to the one of the second post-war. The Southern section of Rome had to be connected, according to the urban architects of that time, to Ostia Sea side through a ship canal tlush to river Tiber, but it was never digged. This canal should have supplied a commercial harbour to rome in the centre (less than 200 mt from the ancient Walls), close to what we call today, Via del porto Fluviale locate on the boundary between Garbatella and Testaccio; in the area close to the canal should have arosen houses for the harbour workers.
