The Leaning Tower of Pisa

Thousands of people visit Pisa’s famous tower each year and wonder just how much longer it can exist without falling.

Millions of dollars have been spent to stop the tower crashing to the ground. Soft, shifting soil has always been the tower’s problem. Recently, it was discovered that the tower had moved two millimeters. This was a great setback because engineers had previously corrected about twenty millimeters of the lean by using an inventive underground cables idea to straighten the tower. Pisa would hate to lose its precious Campo dei Miracoli and the tourist dollars it generates.
