While the reason for its widespread fame is unlikely to have pleased the tower’s original designer, there is no doubt that Pisa’s leaning tower is an international icon and one of the most-visited tourist destinations in Italy.

Tilting 3.99 degrees to the southeast, which puts its roof at 3.9 meters from the vertical, the tower is an architectural masterpiece though it has become a symbol of poor workmanship.

La Torre di Pisa

Standing, awkwardly in the Italian city of Pisa’s cathedral square, The Leaning Tower Of Pisa (La Torre di Pisa in native), as it is properly known, was designed as an unattached bell tower for the cathedral. Its inadequate foundations were dug in 1173 in unstable soil to a depth of fewer than 3 meters and construction took place over the next two centuries in 3 phases probably.

The first floor was built in the style blind arcade where relief of columns is applied to the outer wall, echoing upper floors. When the construction reached the third floor, however, it was apparent that the tower had begun to tilt and building work was stopped. Almost 100 years later, the architect (Giovanni di Simone) was hired to complete the building, and rather than pulling it down and starting again, he continued to build upward constructing subsequent floors slightly higher on one side to counteract the tilt.

-A careful inspection reveals that the tower is, in fact, very slightly curved. 

The tower was completed to the seventh floor by 1319, the final element which is the “bel chamber” was added in 1372 by Tommaso di Pisano who again attempted to counteract the tower’s angle by building the crowning chamber with one side higher than the other.

The result is distinctively quirky, if architecturally fine, building that over the centuries has become recognized around the world.

By the 1960s, the extent of the tower’s lean had begun to cause concern, leading to a conference of international mathematicians, architects, and engineers who were tasked with stopping the famous tower from toppling. In 1990, the tower was attached to the supporting cables on the third floor, tonnes of soil was dug from beneath raised side, and it was pulled back into the same position. The process was repeated in 2008 and foundations strengthened further.

If you are a traveler, then it is a highly recommended booking e-ticket because the Pisa tower gets crowded, currently, the entrance ticket costs around 12.36(USD) per person, so it is highly effective to have an advance booking to visit The Leaning Tower Of Pisa. In a day, you can have a tour of the historic bell tower with amazing sightseeing, you may also climb the staircase inside and explore several attractions around the Pisa Cathedral Square.

It is hoped that this great landmark will be safe for at least the next five centuries!
