The leaning Tower of Pisa is a Romanesque medieval architectural style. The tower was built between 1164 and 1278 on land owned by the Pisani family in Pisa, Italy. It has been described as the first true skyscraper because it resembles a towering stone needle stuck into the earth. The word "skyscraper" came later.
The tower is not only unusual for its lean, but also for its size. At its highest point, the tower is 90 meters (295 feet) tall with an average thickness of about 10 meters (33 feet). It is mostly made up of limestone ashlar blocks that are roughly squared off and have sharp corners. The top three floors are missing, probably due to an earthquake.
The tower is listed as a World Heritage Site and is one of the most photographed landmarks in the world. In 1995, it was voted the most beautiful object in the world by travelers from around the world.
It has been suggested that the tower was designed by Humbert I or his son Hugolino, but there is no conclusive evidence of this.
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 best example of a leaning tower.
It was built between 1173 and 1246 as the main temple of the Catholic Church in Pisa. The original height of the tower was 180 feet (55 m), but over time it has been eroded by wind and weather until it now stands only 115 feet (35 m) high. It has been listed as a World Heritage Site since 1979.
The tower is not actually leaning; it used to be founded on swampy soil that would later absorb the weight of the building. But due to poor construction practices, such as using mortar that was placed too thin to hold the stones together, the tower has settled into an angle of about 3 degrees.
Its appearance has attracted artists and poets for many centuries. Michelangelo is said to have based the design of the Pope's Tomb in Rome's Santa Maria Maggiore on the Leaning Tower. The Italian poet Dante Alighieri included a description of the tower in his Divine Comedy.
The Pisa Leaning Tower is not only one of the most famous landmarks in Piazza dei Miracoli but also the largest standing tower in Europe. The tower leans 3.8 degrees to its north side. It was built between 1173 and 1250 as an observation tower and not a bell tower like many people think today.
The tower comes with two names: Torre di Piazza (Tower of Piazza) and Pisa Touring (tourist trap). No one knows why it's called this way, but both names exist at least since 1877 when the tower became a part of the city's museum system.
During World War II, the tower served as a gun emplacement for Allied forces stationed in Pisa. After the war, it took decades before it was restored to its original state. Now it's one of the most popular attractions in Tuscany.
There are several theories about how the tower came to lean so much. Some say that it's because the foundation is soft underfoot, while others claim that the weight of the building is just not evenly distributed.
The Pisa Leaning Tower Torre Pendente di Pisa, a medieval edifice in Pisa, Italy, noted for the settling of its foundations, which forced it to lean 5.5 degrees (approximately 15 feet [4.5 metres]) off the vertical in the late 20th century. The cause of the tower's leaning is under debate; some say it was built too close to shore, while others point to seismic activity as the true reason. Whatever the case may be, it's been that way since 1333.
The nickname "Torre pendente" (leaning tower) comes from the fact that when viewed from certain angles, it does indeed look like it is leaning. But this is only apparent because you are looking at an angle where the top half of the tower is hidden by the building next to it. If you walk around to other angles, it becomes clear that the tower is standing upright.
There are many more leaning buildings than there are that are known about because people tend to think them dangerous or ugly and don't want to risk their lives by going inside them. This is particularly true in Europe where most leaning buildings are found. There are several reasons why so many buildings in Europe are listed as being "at risk of collapse". One major cause is neglect: those who run businesses often can't afford to keep up with the costs of maintenance, so they fail before they fall down.

John Burland, a British engineering specialist, headed the team. The leaning tower of Pisa is the cathedral's freestanding bell tower in the Italian city of Pisa. The 56-metre structure, famous for its unexpected tilt, took over 200 years to build. Work began in 1173, and five years later it began to tilt. The cause of this was determined much later in history - after the death of Emperor Joseph II in 1790 - when an expert in trigonometry named Gherardo del Rossi calculated that the tower was leaning more than three degrees off true north.
Photographs taken before and after Del Rossi's calculation showed that the tower was indeed leaning, but not nearly as much as estimated by modern surveys. It has been leaning since it was built, due to soil liquefaction caused by overloading the foundation with stone weights used to level the site before construction started. The weight of the building itself is not enough to balance out this effect, which would be alleviated if the tower were higher.
Burland was hired by the Pisan authorities in 1772, just four months before it collapsed under its own weight. He made several attempts to repair the tower, but each time he attempted something new parts of it would collapse. Finally, in 1822, he managed to stabilize the tower so that it could be opened to the public without risk of collapse. That year, he also designed a new entrance gate for the church site.
