In 1173, construction began on the final building of the cathedral complex in Pisa, Italy. The bell tower was designed to stand 185 feet (56 m) tall, but uneven settling of its foundation caused its 5.5-degree lean. Work was suspended several times, but the structure was still leaning upon completion in the 14th century. The tower’s tilt only worsened over time, prompting a recent strengthening project to prevent collapse. How did the tower narrowly escape destruction during World War II? Discuss
