The famous landmark known as the "Leaning Tower" is located in Pisa, Italy. Officially known as the Campanile di Pisa, this iconic structure began leaning during construction in the 12th century due to unstable foundation ground. The tall, circular bell tower stands at approximately 56 meters (184 feet) and is part of the Pisa Cathedral complex. After extensive restoration efforts, the tower is stable and remains a popular tourist attraction, recognized for its unique tilt.
