Leaning Tower of Pisa 'now leaning less'
2018-11-22 16:57:57

Experts have revealed that the Leaning Tower of Pisa, known worldwide for its precarious tilt, is going straight, the BBC reports.

The tower's Surveillance Group, which monitors restoration work, said the landmark is "stable and very slowly reducing its lean."

The 57m medieval monument has been straightened by 4cm over the past two decades, the team said.

"It's as if it's had two centuries taken off its age," Professor Salvatore Settis explained.

Back in 1990, the tourist favourite was closed to the public for the first time in 800 years amid fears it could be on the verge of toppling. At the time, it was tilting by 4.5m from the vertical.

An international committee led by Prof Michele Jamiolkowski, a Polish expert, worked to stabilize it between 1993 and 2001.

By the end, the tilt had been corrected by 45cm, at a cost of £200m.
