The Leaning Tower of Pisa is a tower in Pisa, Italy, famous for its leaning. The tower is located in Piazza del Duomo, next to the Cathedral and Baptistery of Pisa.

The Leaning Tower of Pisa was begun in 1173 as the bell tower of the Cathedral of Pisa. The tower was designed to have 8 floors. However, by the third floor, it was realized that the foundation of the tower was not strong. Therefore, construction was suspended.

Construction started again in 1272. However, the problem with the foundation could not be solved this time either.

Therefore, the slope of the tower gradually increased. The Leaning Tower of Pisa was completed in 1372.

The inclination of the tower was 3.9 degrees at this time. The slope of the tower gradually increased over time. In 1990, it was found that the inclination of the tower had reached 5.5 degrees.

The reasons for the leaning of the Leaning Tower of Pisa are not known for certain. However, as a result of research, it was found that the foundation of the tower was not solid and that there were collapses in the ground.

Among the reasons for the increasing inclination of the Leaning Tower of Pisa are the following: The foundation of the Leaning Tower of Pisa was built on sandy and soft ground. Therefore, the weight of the tower started to collapse the foundation.

Because the foundation of the tower was unstable, subsidence of the ground occurred. These collapses caused the slope of the tower to increase.

The Leaning Tower of Pisa is 55.86 meters high and weighs 56,700 tons. This weight started to further collapse the foundation of the tower.

The Leaning Tower of Pisa continued to lean due to the wind. The wind applied more force to the sloping side of the tower, increasing the inclination of the tower.

Various measures were taken to stop the increasing leaning of the Leaning Tower of Pisa. After 1990, various studies were carried out to reduce the inclination of the tower. As a result of these efforts, the inclination of the tower was reduced to 4.1 degrees.

The works carried out to reduce the inclination of the tower can be summarized as follows: Since 1990, lead blocks weighing 700 tons have been placed on the ground under the tower.

These blocks balanced the weight of the tower and helped to prevent an increase in its inclination.

In 2001, steel cables weighing 600 tons were installed in the ground under the tower. These cables began to be stretched to reduce the inclination of the tower.

In 2003, concrete blocks weighing 700 tons were placed on the ground under the tower. These blocks further stabilized the weight of the tower, helping to prevent its tilt from increasing.

As a result of these works, the increase in the slope of the Leaning Tower of Pisa was stopped. As a result of the studies carried out in 2019, it was determined that the tower could stand more safely for 200 years.

Although the Leaning Tower of Pisa is famous for its lean, it is a solid structure. It is one of the most popular tourist attractions in the world. It is an important part of Italy's cultural heritage.
