Is the Leaning Tower of Pisa starting to straighten up?

CNN/Style – The Italian Leaning Tower of Pisa has quietly begun to defy its moniker, dropping 4 cm of tilt during the last 17 years. The shift, which is around 1.5 inches, is the result of considerable consolidation work done between 1993 and 2001 to correct the tower's sag and maintain it upright.

The news comes just a few months after another major setback for the tower when it was revealed that it will need to be completely restored due to damage caused by the 2011 Tohoku-Pacific earthquake and tsunami.

Pisa's mayor has announced a plan to restore the landmark to its original form by using materials that were available in 1335, when the tower was built. The decision has provoked strong reactions from local residents and experts, some of whom say that the tower is being altered without adequate research into its historical building methods. Others argue that preserving the leaning tower would be impossible because of its structural problems.

The controversy highlights the difficulty in preserving old monuments while also engaging with modern standards of design and engineering. In this case, there are certain advantages to keeping the tower as it is; it remains one of the most iconic buildings in Italy and attracts many visitors every year. However, it does mean that it needs to be maintained constantly, which could cost millions of dollars.

Overall, the situation reveals how difficult it can be to preserve historic sites that have been altered over time through human intervention.

Will the Leaning Tower of Pisa fall one day?

According to experts, the renowned tower of Pisa will continue to tilt for at least another 200 years. It may even remain erect, or almost so, indefinitely. A few ill-advised construction projects hastened the Leaning Tower's inexorably gradual descent over the ages; it slanted 5.5 degrees, its most acute angle ever, in 1990.

The problem is that the tower was not built on solid ground. It stands on swampy soil that is being pushed away from under itself. In time, this process will no doubt stop, but only because there will be nothing left to push against.

There are several theories about what causes this phenomenon known as "torsion" in architecture. Some say that it is an optical illusion caused by how the tower's shadow changes direction with its orientation. Others argue that it is due to seasonal changes in the land underneath the tower. Still others claim that it is due to volcanic activity close by, or even inside the Earth itself.

In any case, torsion is a natural occurrence that can neither be stopped nor reversed, which means that the Leaning Tower of Pisa will always lean slightly towards one side or another. It is therefore safe and sound today and into the future.

This does not mean that the tower will never fall down. On the contrary, it will eventually collapse under its own weight unless someone takes action to prevent it.

How do engineers keep the tower of Pisa from falling?

The tower was stabilized as a result of restoration work completed between 1999 and 2001. Engineers placed weights on the structure's north end while removing earth from below, forcing it to sink back in that direction gradually. The Leaning Tower of Pisa still leans south, although at just 3.99 degrees. It is estimated that it will require about 300 years to return to its original position.

In fact, the tower is so stable that some people say it looks like it's standing on water. The reason is that the base of the tower is not flat but has small hills in it. Water has much less weight than rock and so the tower would appear to be standing on water if it were not for those little hilltops.

The tower is made of limestone and weighs about 22,000 tons. That makes it more than 100 feet high and wide enough for it to be able to support itself almost entirely with its own weight.

Engineers use three kinds of supports to hold up the tower: the bases, which are parts of the ground that the tower rests on; the walls, which are the sides of the tower that face out into open space; and the vaults, which are the rooms inside the tower's body where the stairways and elevators are located.

There are several factors that go into determining how well designed your engineering project is. You need to consider stability when designing structures.

Who was the engineer responsible for the Leaning Tower of Pisa?

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 skyscraper, famous for its unexpected tilt, took over 200 years to build. Work began in 1173, and five years later, it began to tilt. The reason for this unusual phenomenon has never been determined with certainty but many theories have been put forward. Some say it is because the tower is based on Roman principles using brick instead of stone, which would be expected to be heavier than wood. Another theory is that it was done on purpose as an artistic statement by Michelangelo.

The tower comes with two sets of stairs - one for foot traffic and another one for carts. There are also three landings with small rooms where visitors can rest before continuing their tour of the cathedral. The top of the tower offers a view of about 70 kilometres around Pisa and beyond. It is not uncommon to see people taking photographs from different parts of the world with this beautiful backdrop!

You can reach the top of the tower by elevator or you can climb 286 steps (and more than 20 flights of stairs!) But if you do decide to climb up there be sure to wear comfortable shoes because you might need them!

After reaching the top, you will understand why this structure has become a symbol of Pisa and its culture.
