Leaning Tower of Pisa:
- Location: Pisa, Italy
- Description: The Tower of Pisa is the freestanding bell tower of the cathedral of Pisa, known worldwide for its unintended tilt to one side. The tower's tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt increased in the decades before the structure was completed, and gradually increased until the structure was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries.
