About the Leaning Tower of Pisa, an introduction to the Leaning Tower of Pisa

The Leaning Tower of Pisa was built in 1173 by the famous architect Nano Pisano. It is located on the right behind the Romanesque Cathedral and is the symbol of the city of Pisa. At the beginning, the height of the tower was designed to be about 100 meters, but five or six years after the construction began, the tower began to slope from the third floor, and continued to slope until it was completed, and before it closed, the top of the tower was tilted south (i.e., the top of the tower deviated from the vertical line) meters.

In 1990, Italy** closed it down and began to renovate it.

In practice, many experts have conducted a full study of the entire history of the Leaning Tower of Pisa, as well as the building materials, structure, geology, and water sources of the tower, and have used various advanced instruments and equipment for testing. After research, Professor Pilodi, a medieval historian of Pisa, believes that every stone brick used to build the tower is a stone carving, and the bonding between the stone bricks and the stone bricks is extremely ingenious, which effectively prevents the fracture caused by the tilt of the tower body, and becomes a factor that the leaning tower is inclined but does not fall. But he still stressed that the priority now is to understand the mystery of the Leaning Tower of Pisa.

Professor Gehry, an expert who has observed the tower, has speculated based on the rate at which the Leaning Tower of Pisa has been tilting in recent years that the Leaning Tower will collapse after 250 years because the center of gravity of the tower extends beyond the outer edge of the tower's base. However, the Leaning Tower of Pisa Service of the Public Ministry of Public Affairs countered Professor Gehry's argument that mathematical calculations alone were unreliable and that the Leaning Tower of Pisa was "a complex problem of multiple facts". Other researchers have found that the Leaning Tower of Pisa once tilted to the east and then to the south, and they also believe that the tower has not fallen over the past few hundred years, and that it may not be limited to simple assumptions and ** after 250 years.

Of course, it is the Pisan people who are most concerned about the fate of the Leaning Tower, and although they are also concerned about the tilt of the Leaning Tower, they are more proud and proud, proud of having a Leaning Tower in their homeland that considers itself comparable to the famous buildings in the world. They firmly believe that it will not fall, and they have a saying that a pizza tower is as strong and sturdy as a pizza man and will never fall. They were most disgusted by the suggestion to straighten the Leaning Tower again.

For example, in 1934, 90 tons of cement were sprayed into the foundation and its surroundings to implement the foundation waterproofing project, and the tower body was more unstable, moving to the surroundings and tilting faster.

1.Built in 1173, it was designed to be built vertically, but soon after the work began, it was inclined due to uneven foundations and soft soil, and was completed in 1372 with the tower tilting to the southeast.

2.The Leaning Tower of Pisa is located in Piazza Miracolia, north of the city of Pisa, in the province of Tuscany, Italy.

You can go in and read the following encyclopedia about the Leaning Tower of Pisa. Yes.

The Leaning Tower of Pisa (Italian: Torre Pendente di Pisa or Torre di Pisa, English: Leaning Tower of Pisa) was built in August 1173 as a free-standing bell tower of the Cathedral of the city of Pisa, Italy, located in Piazza del Miracoli, north of the city of Pisa, in the province of Tuscany, Italy.

The large lawns of the Piazza de la Miracoli are dotted with a group of religious buildings: the Cathedral (built in 1063-13th century), the Baptistery (built in 1153-14th century), the bell tower (the Leaning Tower of Pisa) and the Necropolis (built in 1174), all of which are clad in cream marble.

The Leaning Tower of Pisa is located behind the Cathedral of Pisa.

The Leaning Tower of Pisa is 55 meters high from the ground to the top of the tower, the width of the bell tower wall on the ground is meters, the width at the top of the tower is meters, the total weight is about 14,453 tons, and the center of gravity is meters above the foundation.

The circular foundation has an area of 285 square meters and an average pressure on the ground of 497 kPa.

The angle of inclination deviates from the outer edge of the foundation by meters, and the top layer protrudes by meters.

The tilt was first discovered in 1174.

Architectural style: The Leaning Tower of Pisa is undoubtedly an important building in the history of architecture.

Its bold circular architectural design had already shown its ingenuity before it was heavily tilted.

Although it is not uncommon for the Italian bell towers of earlier eras to adopt circular foundations, similar examples can be found in Ravenna, Tuscany and Umbria, the Pisa bell tower is considered to be independent of these archetypes, and to a greater extent, it was designed and developed independently of the circular building based on the architectural experience of its predecessors, resulting in a unique Pisa style.

For example, the circular design of the bell tower is thought to correspond to the reflection of the cathedral building on the same side, so it deliberately mimics the curved design of the semicircular apse of the church.

What's more, the bell tower is consistent with the emphasis on the circular structure in the square, especially after the laying of the foundation stone of the grandiose baptistery, which is also circular, and the whole square is more like a modern version of the Church of the Resurrection in Jerusalem (anastasis).

This kind of design is the best in classic ancient architecture.

The decorative style of the bell tower inherits the classic works of the cathedral and the baptistery, the walls are made of marble or limestone into two shades of white bands, the arches of the half-exposed square columns, the carved doors in the arcades, the long diamond-shaped lattice flat roof, and the walls above the arcades face the sunlight to form a strong contrast between the bright side and the shaded side, giving the illusion that the columns in the bell tower are quite heavy.

A visual continuity is created between the cathedral, the baptistery and the bell tower.
