The 294 stairs that ascend in the shape of a spiral on the inner side of the tower walls lead to the summit of Pisa's leaning tower. This well-known work is in the Romanesque style and, as previously noted, dates from 1174. It was built as a place of prayer for members of the Pisan community living in exile in Prato near Florence. The top of the tower is open to the air and views extend over much of Tuscany.
In addition to its artistic value, which makes it worthy of attention even today, the Pisans Tower is important because it shows how people were able to build upright structures before they developed concrete. They used wood, which does not require special techniques or tools for its construction, instead.
The original structure was probably about 70 feet high but now only part of it remains because several years ago someone opened up the interior so that you could climb up the steps.
People go to this site in large numbers because it is easy to get to by foot or car and because of its iconic status. In fact, according to some sources, it is the most photographed building in Tuscany.
However, others say that this isn't true and that another building in Lucca is more popular with tourists. Either way, the Pisans Tower deserves to be included on any list of most photographed buildings in Tuscany.
The Leaning Tower of Pisa is a medieval building in Pisa, Italy, noted for the settling of its foundations, which had led it to lean roughly 15 feet (4.5 metres) off the perpendicular by the late 20th century. The tower has been called Europe's tallest known structure after it was determined that its height is missing from records written before 1872.
It was built between 1173 and 1278 as the main monument of the city-state of Pisa. The original design was probably composed by Humbert I, who was also responsible for the plan of Pisa. The tower has nine floors, including the basement and an attic. It used to have a copper roof but this was removed about 15 years ago due to damage caused by the rain.
The foundation problems of the tower were discovered during renovations in 1763. Engineer Giovanni Antonio Selva decided to remove some earth from beneath one of the corners of the fourth floor and found it to be severely tilted. He continued removing soil and discovered further severe tilts. After investigating these problems, he proposed several solutions, one of which was to drive piles into the ground near the edge of the site and tie the tower to them. This would reduce the strain on the legs that support the top floor and allow the tower to be moved back onto its original axis if necessary.
The Pisa Leaning Tower Torre Pendente di Pisa, Italian Torre Pendente di Pisa, medieval edifice in Pisa, Italy, noted for the shifting of its foundations, which led it to lean 5.5 degrees (approximately 15 feet [4.5 metres]) off the vertical in the late twentieth century. The tower has been called the "Tower of Babel" because of its similarity to other leaning towers throughout Europe.
The first written record of the existence of the tower is dated 1178, but it probably began as early as 1063 when it was apparently built as an observation tower for visiting merchants. The original height of the tower is not known, but it has been estimated to have been about 70 meters (230 feet). Over time, the top three floors of the tower collapsed due to damage caused by lightning. The lower two floors remain intact and are visible today. In 1215, another storm damaged the tower further, this time destroying its top half. The base of the tower remains intact and is what can be seen today.
People have wondered if the tower will collapse ever since it was built. In 1322, the mayor ordered that no work be done on the tower because it was believed to be doomed. In 1772, during the French occupation of Pisa, one side of the tower sagged so far that people took this as evidence that it would soon fall over.
The Pisa Leaning Tower The Leaning Tower of Pisa (Italian: Torre Pendente di Pisa) or simply the Tower of Pisa (torre di Pisa ['torre di' pi: za; 'pi: sa]) is the campanile, or freestanding bell tower, of the cathedral of Pisa, noted worldwide for its roughly four-degree lean, caused by an unstable base. The present structure replaces a 12th-century one that collapsed due to damage from an earthquake. The new tower was built using the same design as the previous one, but with heavier materials and on a more stable foundation. It was completed in 1563 and has been described as one of the greatest achievements in architecture.
The Tower leans because it does not have a solid base. The soil underneath it is porous, and water can seep down into this void. This problem would have been evident even before the earthquake in 1185 because parts of the tower were already leaning at that time. In fact, the top part of the tower is about six inches higher than the bottom part.
People have been curious about the cause of this phenomenon for hundreds of years. Some historians believe that the weight of the tower is not enough to collapse its base because there must be an external force acting upon it. They think that the tower is leaning because it is suspended high above the ground on arches instead of having a solid foundation. However, others argue that if this were the case, the base would have collapsed long ago because the weight of the tower is too much for such small arches to support.
The Leaning Tower of Pisa (Italian: Torre Pendente di Pisa) or simply the Tower of Pisa (torre di Pisa ['torre di' pi: za; 'pi: sa]) is the campanile, or freestanding bell tower, of the cathedral of Pisa, noted worldwide for its roughly four-degree lean, caused by an unstable base. The present tower was built between 1164 and 1246 to replace an earlier one that had been destroyed in a fire. It was designed by Gherardo da Basso, who also designed the cathedral. The Tower has 21 levels, each with a different story told by a decorated panel set into the wall. The top three floors are incomplete and do not contain any bells; they were left that way at the direction of Boniface VIII to prevent people from climbing up to pray. The leaning of the tower is due toward the west.
The first written record of the collapse of this original tower is dated 1321. However, it is believed that the tower was already leaning when it was first built. The new tower was much taller than the old one, but because it was made of dry stone, it used the same unstable base design. The new tower was opened for business in 1246, only to be closed down a few years later after it was revealed that the foundation was still unstable. Work on the new tower was then stopped until 1423, by which time the damage had become irreversible. The new tower was opened for business as planned two years later.
