Leaning Tower of Pisa

The Leaning Tower of Pisa in Italy is going to fall. Scientists travel yearly to measure the building’s slow descent. They report that the 179-foot tower moves about one-twentieth of an inch a year, and is now 17 feet out of plumb. They further estimate that by the year 2007 the 810-year old tower will have leaned too far and will collapse onto the nearby ristorante, where scientists now gather to discuss their findings.

Quite significantly, the word “pisa” means “marshy land,” which gives some clue as to why the tower began to lean even before it was completed. Also—its foundation is only 10 feet deep!
