Question: will the leaning tower of pisa ever collapse?
Answer: Experts say the famous tower at Pisa will lean for at least another 200 years. It may even stay upright well, almost upright forever. ... A few ill-advised construction projects accelerated the Leaning Tower's invisibly slow fall during the past couple of centuries; it tilted 5.5 degrees, its acutest angle ever, in 1990.
