The famous tower in Pisa, Italy, is known as the Leaning Tower of Pisa. This architectural marvel is part of the cathedral complex in the city of Pisa and was originally intended to be a freestanding bell tower. Construction began in 1173 and lasted for about 200 years due to various interruptions. The tower is renowned for its unintended tilt, caused by an unstable foundation built on soft soil. Despite initial concerns about its stability, the tilt has become a defining characteristic, attracting millions of tourists each year. The Leaning Tower was completed in 1372 and remains an iconic symbol of medieval architecture.
