The Leaning Tower of Pisa, located in Pisa, Italy, is a famous bell tower known for its distinctive tilt. It was built in the 12th century and began leaning during construction due to unstable ground. Over the years, the tilt worsened, reaching a staggering 5.5 degrees by 1990. However, efforts were made to stabilize the tower, reducing the tilt to 3.97 degrees. Despite its leaning nature, the tower has become a popular tourist attraction, drawing visitors from all over the world. It's definitely a sight you don't want to miss if you're ever in Pisa!
