Learning tower of pisa

One of the universal symbols not only of Tuscany but of Italy as a whole, the Leaning Tower of Pisa, or rather the bell-tower of the Cathedral of Santa Maria Assunta in the Piazza dei Miracoli, is famous for its characteristic inclination of around 4 degrees, due to a sinking of the ground beneath it that already began in the early stages of construction. The erection of the tower, which stands at 56 metres in height with eight floors, began in August of 1173 and continued for roughly two centuries, with two long interruptions. Resting upon sandy and unstable ground, the bell-tower already began leaning at the level of the third floor, while construction continued in the opposite direction to the inclination. The foundations of the building are attributed to Bonanno Pisano, the man also behind the bronze doors of the Diotisalvi, who at the time was building the After years of studies and works to reduce the Tower’s inclination and ensure its safety, it reopened to the public in the summer of 2001. The Leaning Tower of Pisa is also one of the most famous symbol of Italy all over the world. Pisa and its uniquely beautiful Piazza dei Miracoli, a UNESCO World Heritage site since 1987, have always been a fundamental stop on any holiday in Tuscany. Millions of people come here from every corner of the world every year to try, with the help of perspective, to keep the leaning tower standing. ... More east

© Corbis The Italian city of Pisa is home to the famous bell tower called the Leaning Tower of Pisa. This medieval structure is known for the way it settled, which caused it to lean about 15 feet (4.5 meters) from the perpendicular in the late 20th century. Extensive work was subsequently done to straighten the tower, and its lean was ultimately reduced to about 13.5 feet (4.1 meters). The bell tower was designed as the third and final structure of the city’s cathedral complex. It was meant to stand 185 feet (56 meters) high and was constructed of white marble. Building began in 1173. By the time that three of its eight stories had been completed, however, the uneven settling of the building’s foundations in the soft ground became noticeable. At that time, war broke out between the Italian city-states, and construction was halted for almost a century. This pause allowed the tower’s foundation to settle and likely prevented its early collapse. Bonanno Pisano was the engineer in charge when construction once again began. He sought to compensate for the lean by making the new stories slightly taller on the short side; however, the extra masonry caused the structure to sink further. The project was plagued with interruptions, as engineers sought solutions to the leaning problem, but the tower was ultimately topped out in the 14th century. Inside, twin spiral staircases lined the tower. One had 294 steps from the ground to the bell chamber, while the other had two additional st...

The Leaning Tower of Pisa is one of the most remarkable monuments from the Middle Ages and is an example of Romanesque architecture. The most remarkable feature of the Leaning Tower of Pisa is its famous tilt. As a result of the inadequate foundation, the tower leans at approximately 3.99 degrees southwest from vertical, and the lean was previously growing by 1–2mm per year. Despite this, the tower has remained standing and is a major tourist attraction in Italy. The Leaning Tower of Pisa is 55.86 meters (183.27 feet) tall on the lower side and 56.67 meters (185.93 feet) tall on the higher side. The eight-story tower is composed of a base level and seven distinctive tiers that each have a series of columns and arches arranged around the perimeter in a Romanesque style. There are a total of 207 columns. The first story has 15 arches, the following six tiers each have 30 arches, and the final top bell chamber has 16 arches.

Its fame not only comes from the original trigger for its construction – to show the importance of this city after successfully attacking the city of Sicily, but also from its tilt, which has lasted for more than nine centuries. During this time, numerous people have tried to find the reason why the tower is tilted and how to fix it. It goes without saying that since the very beginning of the tower construction process, there were already existing factors that could cause the tilt. The most important factor at this point in time, and the one that would ultimately contribute the most to the tower’s tilt, is the engineers’ lack of understanding of the soil profile at the tower’s base. Construction began at 1173. At that time, those engineers and architects knew far less about the ground they would construct on than we do now. Ancient Romans used massive stone pillars- piles rested on earth’s stable bedrock. Those architects believed that a three-meter foundation was deep enough as the Tower of Pisa was going to be a relatively short structure. Howev...
