#28: The Leaning Tower of Pisa was leaning before it was finished
The Leaning Tower of Pisa is iconic, but its lean began even during construction in the 12th century. The soft soil underneath couldn’t support the weight of the building, causing it to tilt. After centuries of work to stabilize it, the tower still stands today with its famous lean. While it was meant to be a straight tower, it became known for its charming oddity instead.
