Why Does The Leaning Tower Of Pisa Lean Over?

The Tower at Pisa has been leaning since the early days of its construction. It had only reached a height of 10 metres when the foundations started to slip. Atempts were made to correct this but the structure was completed as a leaning tower in 1350, about 175 years after the work had first started.

North Italy has a number of leaning towers but most of them started leaning quite a while after they were built, so the one at Pisa is unique.

The tower is made from white marble and is nearly 56 metres high and has 8 storeys, each containing 8 bells that sound a different note on the musical scale. It used to be possible, until relatively recently, to climb to the top of the leaning tower of Pisa and look at the view below. This was a strange experience as the tower does lean over at quite a sharp angle. For safety reasons, this is now not allowed.

It started to lean during the construction

The main reason why the tower of pisa lean over is geological reason, that before constructions we have to calculate and estimate the settlement of the construction after completion. There is two type of settlement one due to direct load on the soil and the other which related to time that the load firstly absorbed by the water and then the effect of the load is transferred to the soil particles. Moreover, the settlement in most cases is uneven due to uneven distribution of soil. What we are worried about is the clay particles because it settled and compressed much better than sand. Here what happened in the pisa tower is that the distribution of clay materials underneath the tower is not the same that clay particles are more on the side that comes down more or settled more so the load compressed the clay and compressed in one side more than other side. For this reason it lean over

Lol is it just me or is everyone here a fob:D
The tower leans because of poor construction.
The side that has sunken under the earth was built on wet clay (I thought the Romans were meant to be smart)and when the weight became too great it started to sink.
NOW the Romans realised they had a problem and stopped construction, deciding to let the clay dry before they began again.
Construction then began again and the tower was completed. BUT it started sinking again, you can't blame it it does weigh 14,500 tons.
But luckily we became a bit smarter than the Romans in 2001 and started to give the Tower some support to stop it from sinking any further.
Hope it helps, even though I am about 2 years late:D.

The leaning tower of pisa leans over because of the vast amounts of pizza on the roof that were all shifted to one side during an earthquake and their weight began to make the building lean

My answer  is    because the foundation  wasn't strong because it was  made of clay.

Cause i like pie lol smiley face

Because it was built like that

Because it was made like that

The ground softened

The Leaning Tower of Pisa is leaning because when the tower was built by Bonanno Pisano and community builders it was built on uneven ground so after there was enough weight stacked up it started to sink to one side and that is why the tower leans a whole fourteen and a half feet. Now i am going hit two birds with one stone and the tower has not fallen yet because there is still enough stability but because it has been leaning for 821 years if they do not find a way to stabilize this tower soon it will fall.

Because the soil undernieth
is to soft and the foundation is not dug deep enough.

Because the people who built this tower was stupid

Because it's foundations went soft

The sand under the foundation was loose

The reason for the tower's instability is the sandy soil beneath the foundation. This soil is gradually shifting from under the great weight of the tower. There is a layer of more solid clay 10 metres below the surface. However, the foundation is only 3 metres deep- not clearly enough to stabilize the tower against the shifting soil.

Cause a sumo fell on the top of the tower so it tilted and the sumo fell out

I think it fails at life!!!!!

It is on soil that is uneven

Because the soil dropped on 1 side

Because of the soil

Idk... Blame it on katy perry.

Because it was pushed by president Linken

The soil under is loose and over the years it has tilted.

Because a mole dug underneath and came out the side and he forgot to put it straight when he got out so thats why it leans

The Tower of Pisa leans because once it was being constructed the foundations were not very good and the builders did not measure properly and they only had enough money to build it once so they left it and now it is the unique Leaning Tower of Pisa!!!

The tower leans because one part of soil is stable and the other is kind of clayey.

Because when they built it they made it a tradition

Sciets believe that it leans because of an earth quake, some believe it was build like that

The leaning tower of PIZZA leans because pizza if wobbly

It was built on uneven soil and there was an earthquake

Because of the slip work
