Why Does the Leaning Tower of Pisa Lean?

The Leaning Tower of Pisa is a marble bell tower at Pisa, Italy. Even though the tower has been leaning since it was under construction, it has stood for hundreds of years, despite the fact that it looks as if it might fall any minute.

The tower was begun over 800 years ago, in 1173, and after the first three of its eight stories were built, the ground started to sink, and the tower began to lean. It has continued leaning, a millimeter each year, and now leans 14 feet out of line.

Still, the lean does not stop thousands of tourists each year from climbing its 300 winding steps to the bell tower to view Pisa and the surrounding countryside.

    Yes it would be fun to run up the stairs. I wonder if you’d fall out the window?

    Your at the top with nothing to hold on to, and all of a sudden theres an earthquake! After the quake you feel a slight budge, you look down, only to see that the tower is falling at an alarming rate! What would you do?

    With todays technology the tower will not fall. There has been many things done to correct some of the lean and has already been up righted about 1 in. It will be here well past anyone’s life time who is reading this right now.

    According to the article, the tower is 14 feet out of vertical….
    I hope this is an answer to your posting. I have not idea how many ‘degrees’ that involves, but surely someone reading this posting may have the answer.

    Just checked another web site – sorry I did not write it down – but the Tower leans 5.7 degrees out of vertical. The article further stated that it is expected to collapse in 75 to 100 years [WE won't see it] at which time it will have reached a 6.1 degree angle out of vertical.
    I enjoyed doing this ‘research.’ Fortunately, there were answers everywhere I looked.

  22. Eleanor says

    I gotta say though.
    It is only a tower. I mean I could stick a building block in playdo and get the same result. What a waste of building materials.

    OMG i did not knot that lol i not know that there waz a lady called betra left 60 coins in her will to buy stones to build the tower lol
    and that
    when the workers installed the largest bell of the tower it weight was over 3-and-a-half-tonnes lol and that
    when they were on the 3 story the workers stoped for unknowen reasons lol
    and that
    2 british archatecs used a pump line to determine that the founders inclination is now about 5 degrees

    ok well that is about it and well i know now alot i think because i have a time line on the important dates on the history lol

    oh and dont let me forget that the building of the tower went from 1172-1999

  27. lolzalot says

    because of the soil and mud they biult it on and becoz of the weight on the tower it is on a lean

  28. lolzalot says
