The structure famously known for its leaning position is the Leaning Tower of Pisa, located in the city of Pisa, Italy. This freestanding bell tower is renowned for its unintended tilt, which occurred during its construction in the 12th century due to a poorly laid foundation on soft ground. The tower stands approximately 56 meters tall and features a distinctive Romanesque architectural style. Construction was halted for nearly a century to address the tilt issue, and stabilization efforts have since been implemented. Today, it is a UNESCO World Heritage Site and a popular tourist destination, attracting millions of visitors each year.
