Experts say the famous tower at Pisa will lean for at least another 200 years. It may even stay upright — well, almost upright — forever. That's all thanks to a restoration project, which brought the tower back from the brink of collapse a decade ago.
From the first moment of its construction on unstable subsurface soils in 1173, Pisa's bell tower tilted farther and farther to the south. Its early-onset lean even influenced the way it was built, as its architects tried to compensate by angling the structure northward, resulting in its being banana-shaped.
