Pisa is a small city in the Italian region of Tuscany, a city that has, since the beginning of tourism, been known for just one thing – its Leaning Tower. I stopped off in the town en route from Florence to the Italian capital of Rome, joining the masses to get a look at one of the world’s most bizarre & iconic sights.

The famous Leaning Tower of Pisa is the Campanile (bell tower) of Pisa Cathedral, construction on which began in 1173 during a golden age period for Pisa, a time when the city rivalled Genoa and Venice as a maritime power. Construction continued in 3 phases, taking a total of 173 years to complete. Issues surfaced early in the construction and the tower began to tilt after only 3 of its 7 tiers were completed. Efforts were made to right the tilt (by building higher floors with one side taller than the other) but this only succeeded in creating a second tilt, meaning the iconic tower is slightly curved.
Despite other dubious must-stop-the-tilt efforts, the tower continued to drift at a rate of about 1 mm a year & by 1990 it had reached 5.5 degrees off vertical, a fraction of a degree beyond the critical point at which computer models predicted the tower would fall. The Leaning Tower hadn’t fallen by 1998 at which time its future stability was assured, and with it the Pisa tourist trade, by a combination of soil drilling and biased weighting, meaning the tower won’t be moving any time soon from its present position of 4.1 meters off perpendicular, not even accounting for the efforts of the endless line of tourists aiding the cause by getting that lets-push-up-the-Leaning-Tower picture. Some even help push it up with their feet and some even attempt to right the 834-year-old lean in tandem. Sweet.
