The Leaning Tower of Pisa is a freestanding bell tower located in Pisa, Italy. It is famous for its unintended tilt, which began during its construction in the 12th century due to unstable foundation soil. The tower stands about 56 meters tall and has eight stories, including the chamber for the bells. Construction of the tower started in 1173 and took nearly 200 years to complete. The tilt has been partially corrected through restoration efforts, allowing visitors to safely climb its 294 steps. The tower is part of the Piazza dei Miracoli, a UNESCO World Heritage site, attracting millions of tourists each year.
