Why Is the Tower of Pisa Leaning?

By the time builders had finished the third of eight planned stories about five years later, the tower’s foundation had settled unevenly on the ground beneath it, a dense mixture of clay, sand and shells. As a result, the structure had begun to tilt visibly toward the south.

The Tower of Pisa is a popular monument that has intrigued the minds of many. Located in the Italian city of Pisa, it is known for its distinct lean, due to its unique architecture. The leaning of the tower has been studied by experts from all over the world, as many are fascinated by its unique structure. It has become one of the most recognized architectural wonders of the world, and its history is tied intricately with the history of the city of Pisa.

However, several explanations are given as to why the Tower of Pisa is leaning. The most commonly accepted reasons are primarily related to the engineering of the structure and environmental factors. From a purely engineering point of view, it is believed that the root cause for the leaning Tower of Pisa lies in the composition of the soil on which the tower was constructed.

The region’s subsoil combines clay, sand, and other silt-containing materials. This type of soil is particularly unreliable for building structures of moderate weight, as it tends to compress or expand depending on the pressure applied to it. In the case of the Tower of Pisa, the combination of clay, sand, and other materials caused the foundation of the tower to settle
