2. The Leaning Tower of Pisa holds a significant place in the world history as well. Famous physician Galileo Galilei once dropped two cannon balls of different masses from the Leaning Tower of Pisa to demonstrate their speed of descent was independent of their mass. The leaning tower of Pisa may be leaning because of a blunder committed by the 12 th century engineers, but is still one of the most famous structures known across the world and will always remain so.

3. The leaning tower of Pisa weighs up to 14,500 tons and is actually curved because its builders tried to compensate for its subsidence during construction. During world war II, the tower was used as an observation post by the Germans. The tower witch has been leaning almost since building work first began I 1773. It was closed to the public in 1990 because of safety fears the 183-foot tower was nearly 15 feet off vertical and its structure was found to have been weakened by centuries of strain.

4. The height is low side is 55.86 high side is 56.70 height of walls at base 4.09m and the top 2.48 m weight 14,500lbs 296 or 294 steps. The tower, which has been leaning almost since building first began in 1173, was closed to the public in 1990 because of safety fears.

5. The Leaning Tower of Pisa took a 177 years to complete. It had a three meter foundation is one of the reasons it started to lean. It also had a poor foundation. The reason for this is because of many wars and droughts. The seventh floor was completed in 1319. There is seven bells each a note of the musical scale.
