The tower of Pisa has been leaning for over 800 years. In 1990, engineers projected that the tower would topple if it reached an angle of 5.44 degrees— and the structure was still leaning at 5.5. What gives the tower its infamous tilt, and why hasn’t it collapsed yet?
I’ve seen it in person not very long after the engineers did the work in 1992. I was there in 1998. They still won’t let anyone go near it but the cables are clearly visible that hold it in place. It is a spectacular sight. Surreal even.

With all the flooding, I think this may add to that tilt.
