- An earthquake
- War damage
And, the answer for the the question is :
[STC002987] The simple answer to why the Leaning Tower of Pisa leans is because it was built on a weak base. When construction on the medieval marble tower first began in 1173, the foundation did not settle as was expected. However, in modern times, you are able to ascend the tower’s 294 steps to reach the bell chamber and view the tower’s seven bells. It caused the tower to be off by a significant 5.5 degrees as a result of it. Despite the fact that this was adjusted to a tilt of less than 4.0 degrees, its tilt is still quite evident. It would be extremely unusual for you to visit the tower and not see people posing for photos while holding it up. On the other hand, it’s not easy to say no.
