What Disasters did they face to build the tower of Pisa?

The construction of the Leaning Tower of Pisa faced several challenges, including unstable ground due to the soft, marshy soil of the region, which contributed to its famous tilt. Additionally, the project was interrupted multiple times by wars, financial issues, and political instability in the city of Pisa. Construction spanned nearly 200 years, during which techniques and architectural styles evolved, complicating the process further. Despite these setbacks, the tower was ultimately completed, becoming an iconic symbol of resilience.
