Pizza tower

The Leaning Tower of Pisa or simply the Tower of Pisa (Torre di Pisa) is the campanile, or freestanding bell tower, of th canthedral of the Italian city of pisa, known worldwide for its unintended tilt to one side. It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Squarepiz after the Cathedral and the Baptistry. 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.
