Today, the Leaning Tower of Pisa continues to move backwards and decrease its lean. This is an expected outcome of the restoration works performed on the building. Currently, the tower has a lean that is slightly below 4 degrees, and is predicted to stand strong for another 300 years at least.
The tower began to lean since the soft ground on which it was built could not support its weight.
No, the Leaning Tower of Pisa is not in danger of collapsing for at least another 300 years since efforts have been made to stabilize the monument.
According to computer algorithms, the Leaning Tower of Pisa should have fallen when it tilted to an angle of 5.44 degrees, but it continued to stand even when it leaned at 5.5 degrees. Engineers quickly got to work to stabilize the tower before it collapsed.
Yes, it is safe to visit the Leaning Tower of Pisa as engineers have stated that it's under no immediate danger of collapse.
The current angle of tilt of the Leaning Tower of Pisa is about 4 degrees (3.99 to be accurate).
The Leaning Tower of Pisa is 55.86 meters (or 183.25 feet) tall, although it was meant to be about 60 meters tall.
