Interesting dive into the technology, troubleshooting, and process behind stabilizing the Leaning Tower of Pisa.
In the 90’s, engineers discovered that the tower was extremely close to collapse, within just a few % of the structural limit. They spent a decade researching, experimenting, and developing a solution to permanently stabilize the tower, while also preserving it’s unique features.
Fascinating… TIL the tower was built in three phases and each phase has it’s own tilt due to being corrected for plumb as it went along.
It’s not leaning, it’s curved, which means it’s another opportunity to talk about Peyroni’s Disease. :)

It absolutely wasn’t an opportunity but I respect it none the less.
