Leaning Tower of Pisa Has 300 Years Left
Via Reuters…
The tower’s tilt of about four metres off the vertical has remained stable in recent years, after a big engineering project that ended in 2001 corrected its lean by about 40 centimetres from where it was in 1990 when the project began.
“Now we can say that the tower can rest easy for at least 300 years.”
So how many years does the Grand Canyon have left?
