Reasons Why the Tower of Pisa in Italy Is Tilted

A number of works have been carried out to "straighten out" this building. As a result, the slope of the Tower of Pisa can be lowered to less than four degrees, reported from Britannica.com, Saturday (26/3/2022).

One of the causes of the Tower of Pisa tilting is its location on the ground that is not dense, precisely between the Arno and Serchio Rivers.

The soil consists of clay, fine sand and shells.

The construction of the Tower of Pisa took almost 200 years.

The construction of this tower took almost 200 years, precisely from 1173. This tower is designed to have a height of about 56 meters and is made of white marble.

Reporting from Kompas.com, Saturday (29/2/2020), at first the tower that entered the UNESCO World Heritage Site can stand upright. However, in 1178, the building began to tilt even though the construction process had not been completed.

Three of the eight floors had been completed when the uneven foundations of the building came into view.

War broke out at that time, so the process of building the Tower of Pisa was stopped for almost a century.

The pause is considered to help the foundation of the building to survive, as well as prevent the possibility of collapse early.

Furthermore, the process of building the Tower of Pisa was filled with efforts to overcome the slope. One of them is the new floors that are made higher on the side of the short tower, but it actually makes the building more tilted.

There are seven bells installed in the Tower of Pisa, with the largest bell weighing about 3,600 kilograms.

In the early 20th century, some of the heavier bells were deliberately not activated because it was believed their movements had the potential to aggravate the slope of the tower.

Some engineers predict that the Tower of Pisa will not collapse in the next 200 years, unless there is a strong earthquake in the tuscany and Pisa regions.

For information, the Tower of Pisa is not the only sloping building in the city, quoted from The Travel.

There is also the bell tower of St. Nicola's Church and the bell tower of St. Michele dei Scalzi Church. The two tilted because they stood on the ground that was not dense.
