If we told you to go see a tilting old tower that wasn't Pisa, would you? Probably not, and you should avoid the surprisingly small and devastatingly disappointing Leaning Tower of Pisa too.
Instead, check out the Medieval towers in the town of San Gimignano, a mostly tourist-free haven in Tuscany that's known for its Medieval architecture and perfectly preserved ancient tower houses. In fact, it's often referred to as "the city of beautiful towers," or even "medieval Manhattan."
