The Leaning Tower of Pisa has been leaning for over 800 years and, despite earthquakes, storms and wars, it is still standing.
However, a Team of engineers is constantly monitoring its inclination and people in Pisa are ready to take action to save the Tower should its inclination become critical.
But what is a critical inclination and why the Leaning Tower of Pisa does not fall?

Here are the answers...

The stabilization works for the Tower began in the year 1990 and it took an entire decade to recover some of its inclination.
From over 5°, the lean was brought back to less than 4°. This is considered to be a safe inclination and experts say the Tower can now stand 200 more years without any further intervention.
The stabilization works to fix the Tower were led and coordinated by a group of brilliant minds. Here are the most relevant names...
