Interesting Facts You Probably Didn’t Know About the Leaning Tower of Pisa
Leaning Tower of Pisa is one of the greatest architectural wonders in the whole world that is situated in the charming city of Pisa, Italy. The millions of visitors who come to it every year are doing it to see its special tilt and take that famous photo of holding up the tower. However, behind this iconic landmark, there is a tale that is replete with unbelievable turns, centuries of engineering.

The Leaning Tower of Pisa is not just an architectural accident, but the symbol of survival, innovation and change. Whether you are interested in the historical aspect or architecture or you are just fond of a story, the details about this masterpiece will astonish you.
Read this list of a few of the more interesting little-known facts concerning the Leaning Tower
Pisa
It took nearly 200 years to accomplish.
The Leaning Tower of Pisa was begun in 1173 and it required nearly two centuries before its completion, which occurred in 1372. The prolonged construction time was attributed to wars, financial hardships, and technical difficulties that were occasioned by unstable soil. Ironically, these dislocations became an advantage to it as it allowed the soil to compress and avoid a total collapse of the tower. This halt enabled the builders of the future to implement vital design modifications to save the monument until centuries later.
The Tilt Started Early
It is surprising that the tower started leaning a long time before it was completed. When the second floor was being built, the loose and weak clay soil upon which it was done began to sink irregularly, and consequently it began to tilt. Engineers and architects tried to rectify the lean over the centuries by correcting the following floors and counter weights but the tower kept on tilting gradually. This was a tragic engineering accident that would be the hallmark of the monument, later making it one of the most recognizable monuments in the world.
It Wasn't Meant to Stand Alone
The Leaning Tower of Pisa is not an independent building as most people would assume. It is the bell tower (campanile) of the Pisa Cathedral, which is situated in the great Piazza dei Miracoli (Square of Miracles). The Cathedral itself, the Baptistery, and the Monumental Cemetery (Camposanto Monumentale) are also considered to be part of this UNESCO World Heritage site. The complex of them creates one of the most striking architectural complexes of medieval Europe. When one pays a visit to the area, one can get a full picture of the artistic and religious meaning of the golden age of Pisa.
Not the Only Leaning Tower in Pisa
Although the Leaning Tower is the most known one, the whole of Pisa is surrounded by other leaning buildings owing to the same soft soil. Both St. Nicola Church and St. Michele degli Innocenti reveal the presence of noticeable tilts on both the bell towers due to the same instability of the ground. These lesser known other towers stay as reminders to the visitors that Pisa is not only about a single leaning miracle, but it is a whole city constructed on shaky ground, a metaphorical portrayal of persistence.
Effort in Making the Lean Stopping was successful
Towards the end of the 20th century, the Leaning Tower was tilted at a critically dangerous angle of 5.5 degrees that could cause it to collapse. Between 1993 and 2001, a group of engineers operated on an international scale to execute a large-scale stabilization exercise. They carefully swept away the soil under the high side, and counter-weights to cause the tower gently to lean back. This gave a lower lean at only 3.97 degrees to be sure that it would be safe to generations without losing its iconic slant.
Galileo's Famous Experiment
It is said that the most renowned native of Pisa, Galileo Galilei performed an experiment at the top of the tower to show that falling things of varying weights fall at the same rate. Although there is no written evidence that this ever happened, the tale is an ideal illustration of how the tower was associated with scientific interest and exploration of man. Even today, when people stand on the tower they can envisage the experiments which Galileo was conducting centuries ago when the science of physics was still unborn.
It Moves Over Time
The Leaning Tower of Pisa still sways slightly each year even with the stabilization that has been in place as a result of the natural settling of the soil. Engineers keep a watch on it and by use of sophisticated sensors, the structure is kept stable. Although the movement is very small, only millimeters per year, this slight movement causes the monument to be almost alive and the monument breathes with time. The tower has a current lean of 3.97 degrees and it is viewed to be safe at least within a period of 200 years.
The Tower Stores Survived Earthquakes
It is miraculous that the Leaning Tower withstood several earthquakes. Scientists think that this soft soil which made it tilt provided it with its vitality as well. The ground beneath the tower was absorbing the seismic waves instead of intensifying the shaking and hence the tower was not destroyed. This uncommon occurrence is also known as the so-called dynamic soil-structure interaction effect wherein nature in its blemishes can sometimes act as the savior of man.
It was nearly flattened out
When the tower was being restored in the 1990s, a few engineers suggested that the tower be straightened to eliminate the lean completely. Nonetheless, the plan was widely criticized by the general people and heritage professionals who stated that the tilt was the most iconic factor in the structure. Eventually, it was decided to keep one of the controlled angles and maintain its historical value and image. What they have achieved is a beautiful tower which despite being stable remains beautifully imperfect and continues to thrill millions of people.
