Full Answer

The tower's lean is due in part by an unstable sub-soil and a shallow foundation; however, a restoration team was employed in 1999 that took 11 years to balance the tower and manage its dangerous tilt.

The tower's lean was corrected to a 3.99 degree angle from its previous 5.5 degree angle. The Leaning Tower of Pisa was announced as a UNESCO World Heritage site in 1987.

    In what city is the Leaning Tower of Pisa?

    A:

    The Leaning Tower of Pisa is located in Pisa, Italy. The tower was built in the 12th century and before it became famous for its lean, it was intended to be a bell tower. As the lean became more pronounced over the years, the tower was closed off to the public in 1990 in an effort to try to stabilize it. Considered a success, the project took just over 10 years to complete, and the much safer tower has since reopened to the public.
