The Leaning Tower of Pisa has been falling for eight centuries. Because of this, the Italians themselves call it a "protracted miracle." The deviation increases every year by one millimeter. And the whole building deviated from the axis by more than five meters, which is not so small. But, no matter what, Campanella survived even an earthquake and today is open to the public.
