The Leaning Tower of Pisa, located in Pisa, Italy, is one of the most famous architectural structures in the world. It is a freestanding bell tower that is famous for its unintended tilt, caused by an unstable foundation. The tower began to lean during construction in the 12th century and has been a source of curiosity and amazement ever since.

1. Interesting facts:

- The tower started leaning due to soft ground on one side, causing the foundation to sink. This tilt was noticed even during its construction and attempts were made to correct it, but they only made it worse. Today, the tower leans at about 3.99 degrees from the vertical.

- The tower is made of white marble and stands at a height of approximately 56 meters (183 feet) on the low side and 55 meters (180 feet) on the high side.
