Looking for answers about the Leaning Tower of Pisa, the most special structure in Italy

Leaning Tower of Pisa - Unique architectural work only found in Italy
The Leaning Tower of Pisa (also known as the Bell Tower of Pisa), is an extremely famous attraction and is sought after by many tourists when exploring beautiful Italy. The Leaning Tower of Pisa is located in the city of Pisa, Italy. This tower was built in the 12th century and is an integral part of the Piazza dei Miracoli (square of wonders) complex. The Leaning Tower of Pisa was built in 1173 and took nearly two centuries to be completed.
The tower's construction took a long time because it was interrupted during the war between the Italian city-states. The construction interruption period was about nearly a century. It was not until 1372 that the Leaning Tower of Pisa was completed and put into use. The Leaning Tower of Pisa has a height of 56.67 meters on the south side and 55.86 meters on the north side. The leaning tower includes 8 floors with 294 stairs leading to the top of the tower. The characteristic mark of this tower is an inclination of 5.5 degrees compared to the perpendicular measured in the 20th century. Through many efforts to change and strengthen, today, the inclination of the tower has decreased to less than 4 degrees. degree.
Why is the Tower of Pisa leaning?
The Leaning Tower of Pisa has a very special tilt and makes many tourists curious about why the tower can lean so much. The answer will come from the somewhat different geographical characteristics of Pisa City. The city of Pisa has soft soil with the main ingredients being mud, clay and sand. The Leaning Tower of Pisa was built on soft ground, so it easily tilted. The second reason why the Tower of Pisa tilted was that the tower's foundation was not sturdy enough. Although the weight of the entire tower is up to 14,000 tons, the foundation of the Leaning Tower of Pisa is only about 3 meters deep and is made from a mixture of dense clay.

However, this did not improve the situation and caused the tower to lean more. However, according to many researchers, the soft soil structure that easily causes the tower to tilt is the core factor that helps the Leaning Tower of Pisa experience natural disasters and earthquakes with large aftershocks. According to scientists' calculations, the Leaning Tower of Pisa will not tilt further and will still be safe for at least the next 200 years.

Special things about the Leaning Tower of Pisa that you may not know

The Leaning Tower of Pisa possesses 7 large bells with tones corresponding to 7 basic notes in music theory. The largest bell in the Leaning Tower of Pisa has a mass of up to 4000 tons. Since the 20th century, the bells in the tower are no longer rung. Many scientists believe that the shaking of the bells will cause the tower's structure to become more tilted than its current state.
The Leaning Tower of Pisa has undergone many reinforcements to reduce its tilt
The Italian government has proposed many solutions for reinforcing the Leaning Tower of Pisa. In the early 20th century, people began spraying cement mortar into the tower with various types of bracing and reinforcement, but the tower continued to tilt. In 1990, this project was closed and engineers conducted research on ways to straighten the tower. In 2001, the project reopened and continued to serve tourists. In May 2008, the structure was assessed to have improved its slope by 40 cm and to be stable for at least 200 years.
When you come to the Leaning Tower of Pisa, you will have the opportunity to admire the entire Campo dei Miracoli Complex. This complex includes impressive architectural works besides the Leaning Tower of Pisa such as Duom Cathedral, Camposanto Baptistery and Cemetery, Sinopie Museum and Opera del Duomo Museum. The above works have a Roman beauty and clearly show the unique architectural imprint of the Italians.
