This may be nitpicking, so feel free to ignore it. but St. Peters basilica is in Vatican city, which is it's own country and not part of Italy. But it's a place that you would visit on a trip to Italy, so it's not that important.
Hmmm.....You raise an excellent point. However, the source I used (Google Search) included it as a point of interest in Italy, and I intend to use my data strictly off the list. You're absolutely right though. Thanks for the feedback!
