Leaning Tower of Pisa
Pisa, Tuscany, Italy
One of Italy’s most popular sights, an astonishingly beautiful but leaning belltower dating back to 1173, doomed from the outset having been built on unstable sand and clay. The still-famously titling tower still attracts millions of visitors a year, for the unnerving climb up its 293 steps.
