The Leaning Tower Of Pisa leans because of weak, unstable ground. After the first three levels were built the tower started to lean. It now leans 14 feet out of line and leans 1 millimeter out of line. I hope this answered your question and helps you a lot!
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.
Eng. Smith. 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
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.

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
Well, its mostly because my junk is so big. I went to look over the edge of the tower and it just started leaning and thats how its been ever since. Thats also how the earth keeps its spin, because every step I take the earth can't handle the weight so it gives out and spins.
Construction of the tower occurred in three stages across 177 years. Work on the ground floor of the white marble campanile began on August 8, 1173, during a period of military success and prosperity. This ground floor is a blind arcade articulated by engaged columns with classical Corinthian capitals. The tower began to sink after construction had progressed to the second floor in 1178. This was due to a mere three-metre foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was subsequently halted for almost a century, because the Republic of Pisa was almost continually engaged in battles with Genoa, Lucca and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198 clocks were temporarily installed on the third floor of the unfinished construction. In 1272 construction resumed under Giovanni di Simone, architect of the Camposanto. In an effort to compensate for the tilt, the engineers built upper floors with one side taller than the other. Because of this, the tower is actually curved.Construction was halted again in 1284, when the Pisans were defeated by the Genoans in the Battle of Meloria. The seventh floor was completed in 1319. It was built by Tommaso di Andrea Pisano, who succeeded in harmonizing the Gothic elements of the bell-chamber with the Romanesque style of the tower. There are seven bells, one for each note of the musical major scale. The largest one was installed in 1655. The bell-chamber was finally added in 1372. After a phase (1990-2001) of structural strengthening, the tower is currently undergoing gradual surface restoration, in order to repair visual damage, mostly corrosion and blackening. These are particularly pronounced due to the tower's age and its exposure to wind and rain.
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.
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 short answer is-it was engineered to do so. If they(italy and the historical society for preservation of historical buildings/landmarks) wanted to correct it they could ,even today. But it is a tourist trap so they keep it that way,in fact they did a study on how ot keep it in the exact shape(leaning position) and condition it is in by further anchoring the building. Which many people apparently do not know.even in this day of the internet where this information is readily at hand. : ). Sor to flike turning off and on the niagra falls with a valve to clean and repair it. : ) hahahahah bugs bunny cartooon reference which happens to be true in real life.
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.
6-28-10 On Regis and Kelly show this morning, her and her husband took their family there and she said they thought you were not allowed in the tower but you are! They went inside it.
