Every year, on June 19th, a professor from the University of Pisa climbs to the bell tower and measures the increase in the slant with special instruments. And every year the professor makes the same report: the tower has leaned a fraction of an inch more. Last summer, the 125 foot-high tower was leaning an incredible 15 feet out of line. Scientists say that unless a way is found to stop the tilt, the tower will collapse in less than 80 years.The tower is leaning because the soft subsoil of Pisa will not support it. Its foundation is sinking into the soil at an angle, causing the tower to lean. Since a tremor could shake the foundation loose, the ringing of the tower's bells was forbidden in 1959. Trucks are not allowed to pass in the neighborhood of the tower for this same reason.1.
