The Leaning Tower Of Pissa


The Leaning Tower of Pisa as in Italian they say "Torre pendente di Pisa". in other words we can call it the Tower of Pisa (Torre di Pisa [ˈtorre di ˈpiːza]. it is famous around the world for its unintended lean.

This building is standing behind Pisa's cathedral and in the city's Cathedral Square "Piazza del Duomo" the Tower Of Pisa is the third oldest structure here. The tower's leaning began during its construction, because of insufficient quality and quantity required. for construction. structure on ground was too soft on one side to properly support the foundation's weight. Before completing the structure the tilt was increasing slowly until the structure was stabilized by efforts in the end of 20th and early 21st centuries.

In other words, it "leans" over by 5 meters. If you would stand at the top and drop a stone to the ground, it would hit 5 meters away from the wall at the bottom of the tower. What makes it lean? Nobody knows really the answer. Of course, it wasn’t supposed to lean when it was supposed to stand straight. It was intended as a ball tower for the cathedral which is nearby and was begun in 1174 and finished in 1350.

Even if the tower in the city of Pisa, Italy, didn’t


The height of the tower is 55.86 meters (183.27 feet) from the ground on the lean side and 56.67 meters (185.93 feet) on the other side. It is built of entirely white marble, The walls are 2.44 m (8 ft 0.06 in) thick at its base. It has 8 stories, which in Pakistan would be about the height of a 15 storied building. It is approximately 14,500 metric tons(16,000 short tons) in weight.  There is a stairway built into the walls consisting of about three hundred steps; which leads to the top. And by the way, those people who climbed these stairs to the top get the magnificent, view of the city and of the sea, which is about 9.5 kilometers away. At the top the tower is 5 meters out of the perpendicular. On the north side staircase of the seventh floor there has two fewer steps. The top of the tower is 3.9 meter (12 ft 10 in) displaced horizontally because the towers now tilted about 3.99 degrees from the center.

The foundation of the tower were laid in the sand, and this may explain why it lean's. But it didn’t suddenly begin to lean. This began to lean when only three f its stories, or "galleries" had been built so the plans were changed slightly. In the last hundred years, the tower has leaned 0.3 meters more. Some engineers say that it should be called "the falling tower", because they believed that it will eventually topple over.


There has been different views, theories or controversy from people about the real identity of the structure and construction of the Leaning Tower of Pisa. The design was  allocate to Guglielmo and Bonanno Pisano For many years, in Pissa he is a great resident artist in 12th-century, many people known him for his bronze casting, specially in the Pisa Duomo. He went to Monreal in 1185 left Pisa, Sicily, only to come back and die in his home town. in 1820 right at the foot of the pissa tower his name was found on a piece of cast. but many people think that may be its belong to the bronze door in the facade of the cathedral that was destroyed in 1595. In 2001 a name Diotisalvi came to light that was the original architect, as at the time of building and empathy with other Diotisalvi works. especially the bell tower of Baptistery and the San Nicola.


Construction of the tower arise in about 200 years and in three stages. work of campanile began On 14 August 1173 on the ground floor of the white marble, at the time of military success and welfare. This ground floor is a blind arcade articulated by engaged columns with classical Corinthian capitals.

In 1178 when the construction was completed on ground floor and first floor the tower began to lean right at the time when construction had progressed to the second floor due to a mere three-metre foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was eventually halted for almost 10 decades, because at that time the Republic of Pisa was busy in fights with Florence, Genoa, and Lucca. This let time for the underlying soil to resolve. Otherwise, the tower would almost certainly have fall. On the unfinished construction third of the third floor clocks were installed in 1198.

Giovanni di Simone, who also was the architect of Camposanto restarted the construction of pissa tower In 1272. to give a try to compensate the tilt, for that they came with the solution to built upper floors with one side taller than the other. and that's the reason the tower became curved. In 1284 When Genoans defeated pisans the Construction was stopped again.

In 1319 the construction of seventh floor was completed. Then in 1372 the bell-chamber was finally installed by Tommaso di Andrea Pisano, who achieved to make Compatible the Gothic elements of the bell-chamber with the unique Romanesque style of the pissa tower. In total seven bells are installed but the largest one was installed in 1655. these seven bells are one for each note of the musical major scale.

After a long period of structural strengthening, The tower is presently undergoing gradual surface rehabilitation, in order to renovate the visible damage, mostly corrosion and blackening. These are especially marked because of its exposure to wind and rain and the tower's age.
