Tourists visit the leaning tower of Pisa, free of scaffolding, April 26, 2011.

Tourists take pictures on Miracle's square with the leaning tower of Pisa, free of scaffoldings for the first time after 20 years of stabilization and restoration work, April 26, 2011. Legend has it the tower was begun in 1173 after a Pisan noblewoman left 60 coins to the city in her will to build a magnificent belfry. But after just three levels had been built, the tower began to lean, sinking into its foundations on one side. Though panicked architects and engineers have been trying to stabilize it ever since, the tower has continued to tilt.
