Piazza Navona
The third and final teenage hang-out spot we visited was the Piazza Navonna which was once a chariot racing track. There are a lot of strange folk running around here but I actually like this place though. There are musicians, jewelry sellers, magicians, living statues and lots of artists trying to make a buck off the tourists as well as the locals. The area is full of people but it encompasses a large area so you can get away.
