The Sinking Bell Tower is a notable structure located in the town of Pisa, Italy. It is part of the Piazza dei Miracoli and is famous for its unintended tilt, which began during its construction in the 12th century due to unstable foundation soil. The tower stands at approximately 56 meters tall and features a series of elegant arches and columns. The tower is primarily known as the bell tower of the Pisa Cathedral. It has eight stories, including the chamber that houses the bells. Restoration efforts have been made over the years to stabilize the structure and prevent further sinking, allowing visitors to safely admire its unique architectural beauty.
