I would pass by this church every day on my way to school, and it always took my breath away. The facade is not as extravagant as some other churches in Rome, but just knowing that it is one of the oldest of its kind is impressive enough. The square is great to sit in and people watch, since it's a nice mixture of tourists and neighborhood residents going about their day. Aside from the annoying peddlers, this church is a must-see in Rome.
