Pisa's Miracle square with its leaning tower at right on Dec. 2, 2010. The scaffolding is about to come off the Leaning Tower of Pisa following a painstaking two-year restoration that has restored the medieval masterpiece to its former glory.

In addition to the stabilization, the tower also got a good cleaning. The tower construction began in 1173, but was already tilting when the third level was finished due to soft clay under its foundation. They continued despite the leaning, but in 1990 they had to close the tower because it was leaning a little too far. It opened again in 2001 though restoration was in progress.
