Via el Corso (the ancient via Lata), commonly known as the Corso, is the main street running through the historical centre of Rome, Italy. It is remarkable for being absolutely straight in an area characterized by narrow meandering alleys and small piazzas. It is also wider than most streets in the centre of Rome, but still only has barely room for two lanes of traffic and two narrow sidewalks. The northern portion of the street is a pedestrian area. The length of the street is roughly 1.5 kilometres.
