Fall of the Leaning Tower (#2611)

Even before it was finished 800 years ago, the Leaning Tower of Pisa, a masterpiece of medieval architecture, began to topple, shaken by earthquakes and sinking slowly into the unstable soil. Today, the top hangs just 16 feet over the base and collapse seems imminent. NOVA follows a decade-long search for a solution to correct the lean and save the unique building. State-of-the-art computer models, ingenious experiments with models and a string of near-disasters eventually push an international committee of prominent engineers and architects into an eleventh-hour decision.
