A building that leans but doesn't fall

Construction of the Leaning Tower of Pisa began in 1173 and lasted nearly two centuries. Originally intended as a freestanding bell tower for the nearby cathedral, the tower began to lean to the southeast due to unstable ground and poor foundation. The lean was caused by a combination of factors, including soft ground and weak mortar used in construction. Despite the gradual lean, the tower did not fall for several reasons, such as its shallow foundation and the soft ground acting as a cushion. Efforts to straighten the tower in the 20th century, including soil removal and counterweights, helped stabilize it. Today, the Leaning Tower of Pisa remains a popular tourist attraction, showcasing the ingenuity of its builders and the unpredictability of nature.
