ROME – The leaning tower of Pisa is now less bent than it was before thanks to engineering work implemented 17 years ago to reinforce the structure, a geo-technician working with the building’s surveillance group told EFE on Thursday.
The emblematic Italian landmark in the city of Pisa (central Italy) has lost four centimeters (1.5 inches) of tilt after it underwent engineering works and is straighter than it was before, meaning many future generations will potentially carry on enjoying the bendy building.
Nunziante Squeglia, geo-technics professor at the University of Pisa and member of the building’s surveillance group, told EFE that the tower appears to be straightening between 1 and 2 millimeters a year on average.
The most important consequence of the engineering work is that the building has become much more stable than the surveillance group could have hoped for.
Squeglia also assured EFE the iconic tower would not fully straighten and that based on the figures, it would need over two centuries to become upright.
The Pisa tower is monitored hourly through data that surveillance instruments send to computers in order to keep track of oscillations and vibrations caused by possible earth tremors.
In 1993 experts decided the tower would need reinforcement due to the massive difference in angle between the top and bottom which was putting the building at risk of tumbling.
The Tower of Pisa is a freestanding bell tower of the cathedral of the Italian city of Pisa.
