text: Tower of Pisa\nThe tilting of the structure is not new. Soon after this 800-year-old campanile (free standing bell tower) was begun, workers noticed a risky inclination caused by soft subsoil. Partial remedies were applied and the architecturally flawed tower was completed about 70 years later.\nOver the centuries the tilt angle of the 56-meter (182-feet) tall Leaning Tower of Pisa continued to increase. Today the top edge lists about 5 meters (16 feet) from the perpendicular, creating a gravity-defying appearance.\nSome experts predict an any-year-now collapse, others believe that the current restoration project will save this world wonder.
