The Leaning Tower Of Pisa: Italy’s Legendary Architectural Mistake | Massive Engineering Mistakes
Did you know that The Leaning Tower of Pisa in Italy was actually the result of a human mistake? Just one minor miscalculation made in the 11th century left us with an amazing 14,500-tonne leaning tower. Find out how this mishap came about here.

Why doesn’t the Leaning Tower of Pisa fall over? - Alex Gendler
Dig into the 800 year history and architecture of the Leaning Tower of Pisa and find out what gives the tower its infamous tilt.
--
In 1990, the Italian government enlisted top engineers to stabilize Pisa’s famous Leaning Tower. There’d been many attempts during its 800 year history, but computer models revealed the urgency of their situation. The tower would topple if it reached an angle of 5.44 degrees— and it was currently leaning at 5.5. What gives the tower its infamous tilt? Alex Gendler explores the monument's history.

The famous leaning tower at Pisa has stood for hundreds of years without falling over - although it recently came close to disaster! Did you know it took almost 200 years to build this tower because of problems during its construction? Despite its difficulties, the leaning tower has become a popular tourist destination, and during restoration efforts engineers were not allowed to straighten it all the way so that it would continue to lean.

How the Leaning Tower of Pisa Was Saved: Crash Course Engineering #40
This week we’re going underground to explore geotechnical and seismic engineering. We’ll look at how structures connect to the ground and transmit loads through their foundations, and how those foundations need to provide a high bearing capacity. We’ll see how properties of the soil, like shear strength, affect bearing capacity. We’ll also consider happens when the ground experiences stress from seismic activity and how seismic engineers work to counteract those effects.

9th August 1173: Construction begins on the Leaning Tower of Pisa
By the twelfth century, the city of Pisa had become an important sea port and one of the four main historical maritime republics of Italy. Its sizeable fleet secured a commercial and political influence that extended across the Mediterranean, allowing Pisa to gain considerable wealth.
As a sign of this prosperity the city began construction of a religious complex, the Square of Miracles, which would be dominated by a mighty cathedral and its free-standing bell tower or campanile. The cathedral was consecrated in 1118, but work didn’t begin on the campanile for another five decades. The foundations were eventually laid on 9 August 1173.
The most notable feature of the tower is its tilt, which first became apparent with completion of the second floor in 1178. The ground beneath the tower i...

By the twelfth century, the city of Pisa had become an important sea port and one of the four main historical maritime republics of Italy. Its sizeable fleet secured a commercial and political influence that extended across the Mediterranean, allowing Pisa to gain considerable wealth.
As a sign of this prosperity the city began construction of a religious complex, the Square of Miracles, which would be dominated by a mighty cathedral and its free-standing bell tower or campanile. The cathedral was consecrated in 1118, but work didn’t begin on the campanile for another five decades. The foundations were eventually laid on 9 August 1173.
The most notable feature of the tower is its tilt, which first became apparent with completion of the second floor in 1178. The ground beneath the tower is weak and unstable and, with the building having just 3 metres of foundations, its weight had begun to compress the soft subsoil.
In an attempt to correct the lean, the upper floors of the tower were built with one side slightly taller than the other. However this only led to the tower sinking even further, increasing the angle of the tilt that eventually reached more than 5 degrees in the 1990s.
In response to the imminent threat of the tower toppling over, a team of engineers eventually chose to remove more than 70 tons of soil beneath the raised side of the structure. This allowed the famous tower to straighten slightly, returning to an angle where it became safe for the public to climb the 294 steps inside. It continues to be one of the most popular tourist attractions in Italy.
