The LEANING TOWER!
I’m not going to fool you, Pisa’s all about the famous LEANING TOWER! Yes. But it doesn’t mean you should ignore it. While in Tuscany, it’s simple to get to, and it won’t take you much time out of your probably busy schedule, even if it’ll be just for a quick picture when you pretend to keep it from falling. Lucky you!
