Leaning Tower of Pisa Facts


The Leaning Tower of Pisa is also called Torre pendente di Pisa in Italian or simply Torre di Pisa (Tower of Pisa) and it is the freestanding bell tower or campanile, of Pisa’s cathedral. This landmark is very well-known because of its unintended tilt form. If you want to know where is the Leaning Tower of Pisa located, it is at the rear side of the Cathedral and it is the Cathedral Square’s third oldest building (next to the Cathedral itself and the Baptistery).

One of the most commonly known Leaning Tower of Pisa facts is that its tilt started during its construction. The ground it was built upon was too pliable on one side and thus there was inadequate foundation to support the weight of the structure.

The ground was soft subsoil and it had difficulty in supporting the 14,500 ton weight of the tower. The tilt became more noticeable and got worsened when a second story was added. The tilt continued to increased before the completion of the project until it eventually stabilized and corrected partially through efforts done in the late 20th century to the early 21st century.
