Almost every visitor to Rome passes through the Piazza Venezia and admires the city policeman who stands on a round platform directing the apparently chaotic traffic. What few people know is that over the years the round platform has been destroyed over and over again by being run into at night by cars, lorries and even motorcycles. This will no longer happen, a new platform has been built which is a lift which can be lowered into the ground when it is not in use.
