Surprising change to Leaning Tower of Pisa
THE Leaning Tower of Pisa isn't leaning so much anymore.
Experts have revealed the tower has lost 4cm of its tilt and is not in immediate danger of falling over anymore, after more than two decades of restorations due to safety fears, The Sun reports.
The white marble 55 metre tower is known around the world - and was famously straightened by Superman in the 1983 movie Superman III.
At one point it was feared subsidence would send the historic building crashing to the ground but a series of projects have halted the droop and it is now thought to be reasonably stable.
A team of specialists led by professor Nunziante Squeglia, a geotechnics expert at the University of Pisa, have announced the findings after a 17-year study.
He said the tower's health was better than forecasted, and added "the stability of the bell tower is more than expected".
The 800-year old tower was closed to the public for ten years in the 90s as part of a $A39 million restoration project to halt the tilt.
Cables were used to secure the monument and the stairs, which offers tourists a breathtaking view of the rolling Tuscan countryside.
Since it was built it has survived four major earthquakes and experts say its tilt is now just under four degrees and it is off centre four metres from vertical.
Giuseppe Bentivoglio, from the Opera Primaziale organisation that preserves the tower said: "It was on the verge of collapse, but we managed to stop the tilt and secure it."
Boris Johnson was spotted at the tower in the summer and more than a million people visit the tower every year which is a UNESCO World Heritage Sight.
