Pisa's leaning tower will not fall for 300 years

The famous tilting tower Italy has been fixed safely and is no longer dangerous for at least 300 years, the country's engineers said.

The 4-meter-sloping construction of the vertical axis has stood firm in the last few years, after a major renovation project ended in 2001, thus adjusting the inclination to about 40 cm from 1990 when the project started. .

"Now we can confirm that the tower will stand for at least 300 years," said Michele Jamiolkowski, Italy's leading engineer.

The tower has not been open to visitors for nearly 12 years since 1990, when it has subsided about 1mm per year. By December 2001, the project was reopened after the largest restoration project at the time.

The 14,000-ton bell tower, a national symbol along with the Colosseum in Rome, was built in several stages from 1174 to 1370. It started to tilt after completing several floors due to the foundation be solid. Initially the masons used trapezoidal stones to pull the building vertically, but the tower continued to tilt.

During the restoration project that ended in 2001, the building was anchored by cables, and cement was inserted to reduce pressure on the ground. The tilt of the tower is now considered safe and returns to the status quo as in 1700.

Italian officials have long claimed that they do not plan to erect the tower because it will undermine the uniqueness of the building.

Galileo astronomer, once sanctioned by the Vatican for announcing that the earth is orbiting the sun, used this tower to conduct experiments on gravity.
