The thing about the leaning tower of Pisa that we know intuitively is that the whole thing was a big mistake. Weak foundations mean buildings fail over time. But this one has been a massive success for the very fact that it’s still standing, if off-kilter, despite the fatal design flaw. It’s perfectly imperfect and thus appealing—for who among us is perfect?

Pisa is a one hit wonder on the tourist circuit. Most people swarm in, head straight to the tower and leave shortly afterward. Plenty of kitschy trinkets for sale on the gauntlet between parking and the tower. This is the modern hazard of international travel to popular destinations: aggressive tchotchke vendors.

The tower itself is the destination, and it shocks the senses when you actually see it up close and personal. To climb it, feeling that distinct lean in every step to the top, is quite unusual and a bit thrilling. We’ve climbed stairs before, but never an off-kilter spiral like this one. You know immediately why people come here to see and climb it. Perfection is in the eye of the beholder.
