Souvenir magnet pictures the famous leaning tower in Pisa, Italy. Completed in 1319, the Pisa Cathedral's bell tower might have toppled if not for a century-long interruption in construction. From 1178 to 1272 Pisa was too preoccupied with military struggles to worry about the sinking tower. By the time relations with its neighbors had settled, so had the subsoil.
A restoration project completed in 2001 reduced the lean by 18", from 5.5 to 3.99 degrees. In 2008 additional earth was removed from beneath one side and engineers report the tower has stopped moving for the first time in its history. It is expected to refrain from toppling for at least 200 years.
