The Leaning Tower of Pisa is one of the most remarkable architectural structures from medieval Europe. Until now, the tower has survived many strong earthquakes due to the softness of the foundation soil, that makes vibrational qualities of the structure to be changed significantly, and thus the Tower does not resonate with seismic tremor ground movement.
Now, experts have come with surprising news that the Leaning Tower of Pisa is going straight. The 57m (186ft) medieval monument has been straightened by 4cm (1.5in) over the past two decades, revealed experts.
There was a time when its distinctive tilt was so extreme, experts were worried the structure would soon collapse, and so a plan was carried out to pull the tower further in line.
Those efforts ended back in 2001. Since then, the building has continued to straighten, with new data saying the tower as recovered around 4 centimeters (1.5 inches) or about half a degree of lean.
Nunziante Squeglia, a professor of geotechnics at the University of Pisa who works with the surveillance team, added: “What counts the most is the stability of the bell tower, which is better than expected.”
Of course, it’s still not straight. Nobody would want to visit the Perfectly Perpendicular Tower of Pisa after all.
