The most famous example is the Leaning Tower of Pisa, located in Italy, which began to lean during its construction in the 12th century due to unstable foundation soil. This iconic structure attracts millions of tourists each year, eager to witness its remarkable design and historical significance. These towers often symbolize the challenges faced in engineering and construction, showcasing how human ingenuity can adapt to unforeseen circumstances. Other notable leaning towers include the Tower of Pisa and the Leaning Tower of Suurhusen in Germany, each with its own fascinating story and architectural style.
