The Tower has been leaning for a subsequent amount of years due to faulty infrastructure and soil perk erosion. The weight load on the surrounding area's of Wall density/mass in correlation to ground stability is in question.
The building of the tower started in 1173, and began leaning before its construstion was completed in the 14th century.
hope that helps

The Tower of Pisa leans sideways because it was built on unstable soil. The building began to lean as soon as the first three floors were completed. Nevertheless, building continued and the seven-story structure was finished between 1360 and 1370. The tower leans a little bit more each year and was closed for repairs in 1990, when it was leaning fourteen and one-half feet to one side. Engineers worked to stabilize the foundation, straightening the tower only slightly to help prevent irreparable damage without taking away the uniqueness of the structure. The tower's characteristic angle has attracted thousands of visitors to Pisa throughout the ages.

In the past it was widely believed that the inclination of the Tower was part of the project ever since its beginning, but now we know that it is not so. The Tower was designed to be "vertical", and started to incline during its construction.
The leaning tower of Pisa leans beacause the foundation of the tower was built in unstable soil. The other reason is because the foundation was not dug deep enough.

The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and it is the third structure by time in Pisa's Piazza del Duomo (Cathedral Square).
ANSWER:The Tower of Pisa was a work of art, performed in three stages over a period of about 177 years. Construction of the first floor of the white marble campanile began on August 9, 1173, a period of military success and prosperity. This first floor is surrounded by pillars with classical capitals, leaning against blind arches.The tower began to sink after construction progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil. This means the design was flawed from the beginning. Construction was subsequently halted for almost a century, because the Pisans were 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 higher floors with one side taller than the other. This made the tower begin to lean in the other direction. Because of this, the tower is actually curved.[4] 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. The bell-chamber was not finally added until 1372. 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 scale. The largest one was installed in 1655.
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 strong due to the tower's age and to its particular conditions with respect to wind and rain.
REAL REASON : DURING THE CONSTRUCTION THE SOIL WAS VERY marsh WHICH CAUSED IT TO CURVE .

The soil was too soft and not stabilized when it was built. It has now been stabilized so it won't lean any further. They could straighten it but chose not to because it would no longer be a tourist attraction.
