Leaning Tower of Pisa!

The Leaning Tower of Pisa, built as a bell tower, began construction in 1173. By 1178, as the third floor was completed, builders noticed the structure tilting. The issue lay in its 3-meter foundation, set on soft clay and sand that couldn’t support its weight. Rather than abandon the project, they adjusted the upper floors to counterbalance the tilt, giving the tower its distinctive curve. Over time, the lean increased as the foundation continued to settle unevenly. Despite this, the tower remained standing, thanks to the slow, 199-year construction process, which allowed the soil to stabilize, and the clay foundation, which absorbed seismic shocks. By 1990, the tilt reached 5.5 degrees, prompting fears of collapse. Restoration efforts between 1993 and 2001 reduced the tilt to 3.97 degrees, securing its future. Today, over 600 years since its completion, the Leaning Tower of Pisa stands as a unique piece of medieval architecture and a popular tourist destination.
