Why does the Leaning Tower of Piza(比薩斜塔)in Italy lean(傾斜)?It leans because of a mistake.It has leaned almost since the day the tower was built.In 1174,the people of Piza,Italy wanted to build a bell tower.They wanted the tower to be the most beautiful bell tower in all of Italy.The city also needed a bell tower because the church(教堂)did not have one.As soon as the first floor of the building was finished,the tower started to lean.Builders tried to make the building straight again as they added(增加)more floors,but the Leaning Tower only got worse as the tower grew.It look almost 180 years to finish the tower.Today,the Leaning Tower has eight floors.It is 54.5 metres tall,and it leans almost 4 metres to one side.The tower is also sinking(下沉)into the ground on which it was built.Every year,the tower leans another 1.5 centimetres.
