The Tower of Pisa is a popular spot in Italy. It’s tall – 56 meters – and leans a lot! The top of it is over four meters off from straight up and down. But why does it lean so much?
The answer goes back to when it was built in 1173. It was built on shaky ground. The base of it was only three meters deep. When they were building it, the ground moved and sank a little. This made the tower lean. They tried to fix it, but it still tilted.
Over time, the lean got worse. In the 1990s, it leaned 5.5 degrees – very dangerous. To stop it from falling over, some soil was taken out from under the tower, and weights were used to balance it. Now it still leans, but only 3.99 degrees.

The Story Behind the Lean
The leaning Tower of Pisa or the Torre Pendente di Pisa, a standing bell tower in Pisa, Italy, is known for its tilt. The lean of this tower has baffled visitors for years.
It all started when the tower was built in 1173. The whole construction took almost 200 years! It was built on soft, quick-to-move soil, which caused a lean pretty quickly. The lean was not planned, but it got worse as the tower went up.
Throughout the years, several attempts to fix the tilt died out. In the 1900s, due to safety risks, folks couldn’t visit, but much work was done to steady this tall structure.
Now, the tower is still a hit with tourists; with millions drawn to it every year. Even with its tilt, it stands as a mark of the smarts and grit of its creators.
The Leaning Tower of Pisa is a standalone bell tower in the Italian city of Pisa. Its lean, a mix of factors related to its design, makes the tower unique.
The architects envisioned a round bell tower of eight floors, rich with arcs. But the base—layers of soft soil, clay, and sand—was far from sturdy for a structure so heavy and tall.
They planned a curved base and one side higher to balance the lean. The goal was to hold the tower straight.
But the tower tilted during the build due to the soil’s softness and the tower’s weight. When more weight was added to the tower’s higher side to fix the lean, it only worsened.
Eventually, the lean risked toppling the tower. In the 1990s, a group of engineers and architects toiled to keep the leaning tower from tipping. Techniques like soil removal from the foundation and weight addition to the lean’s other side were employed.
The tower leans today but it’s a lot steadier. Go up the tower and see amazing views of Pisa, relaxed in the fact that it’s safer due to modern engineering and architecture.
Building and First Leaning
They began building the Leaning Tower of Pisa in 1173. It took almost 200 years. It’s foundation was soft clay, sand and shells – not strong enough for a heavy tower. The foundation was only three meters deep, too shallow for such a large structure.
During building the tower started to lean. They noticed it when the third floor was being built. The builders tried to fix the tilt by making the upper floors a bit taller on the leaning side, but it made it worse. Each new floor increased the leaning.
The leaning was due to the soft ground which couldn’t hold the tower’s weight. The ground on the tower’s south side was softer than the north side, causing the tilt toward the south. The south side started to sink which made the lean worse.
In 1990, they closed the tower to visitors for safety. Engineers worked to make the tower safe. They took soil from under the north side of the foundation, which lessened the tilt by 44 centimeters. They also put weights and cables in place to stop further leaning.
The tower now tilts at around 3.99 degrees, less than before fixes were made. It’s open for people to visit, and from the top, you can see the beautiful city of Pisa and nearby landscapes.
Further Leaning and Fixing
Lean Correction Attempts
When people realized the Tower was tilting, many tried to correct it. In 1935, filling the foundation with cement was tried to steady the Tower. However, this made it lean more. In 1990, a big project started to steady the Tower and stop it from falling over.
This project involved taking soil from the Tower’s north side and placing lead weights on the south side. This was to balance out the tilt. The Tower was then moved upright by 44 centimetres, and it’s tilt was reduced by 45 centimetres. The project worked, and since then, the Tower hasn’t moved much.
New Ways to Keep It Safe
Nowadays, the Tower is checked often to make sure it stays steady. People use the latest methods to look after the Tower and stop more damage. It’s fitted with devices that track the tilt and movement, and this information is used to check changes in the lean.
There have also been changes to the area around the Tower to stop more sinking. The soil around the Tower has been packed down, and a drainage system was put in. This stops water from gathering and making the soil move.
The Tower of Pisa is famous and often visited because it leans. This has made people curious for 800 years, and it probably will for another 800 years.
Effects on Tourism
People from all over the world want to see The Leaning Tower of Pisa. The reason? It leans! And that makes it a powerful symbol of Italy.
Because of the tower, Pisa is a thriving tourist city. The crowds of tourists benefit local businesses and bring in lots of money. The Tower itself generates millions through tourism.
But, the lean is also a problem. It’s uncertain, and the tower might collapse. To stop that from happening, people work to restore and stabilize the tower. They want to keep it safe for people to visit in the future.
Even with the slight danger, people are still drawn to the tower. They love it for its tilt. It shows the tower’s appeal is more than a passing curiosity.
It’s More than a Tower
The Leaning Tower of Pisa isn’t famous only because it leans. It’s also a symbol of Italy. It’s visited by millions each year, making it more than just a tilted attraction.
Have you seen the tower in movies, TV shows, and books? Seeing artwork of it like paintings and sculptures? That famous iconic tower is the Leaning Tower of Pisa.
Local folks and tourists love how it’s tilted. Snapshots of them seeming to prop it up or topple it are quite popular!
But the tower is more than just a fun photo background. Despite earthquakes, wars and the ticking of centuries, it still stands! Human ingenuity and perseverance made this possible. We can thank the architects, engineers, and builders’ skill and hard work.
In a nutshell, everybody around the globe is engaged with the Leaning Tower of Pisa’s distinct flair and lasting impact. You should really go to Italy and see it if you can!
Why does the Leaning Tower of Pisa lean?
It’s because it sits on weak groundwork. The tower’s foundation was too soft. So, while it was being built, it started to lean due to its weight.
How does the Leaning Tower of Pisa lean without toppling over?
The Leaning Tower of Pisa stands because of a special design structure. It has eight floors, each smaller than the one beneath it. This helps to evenly spread the tower’s weight, stopping itself from falling.
Does the Leaning Tower of Pisa tilt more each year?
Nope, it doesn’t. Actually, the Leaning Tower of Pisa is becoming straighter. Experts have limited its lean. They used different techniques like taking out soil underneath and also added counterweights.
Is the Leaning Tower of Pisa open to the public?
Yeah, you’re allowed to go inside. There’s a spiral staircase that winds up to the top. It’s got 294 steps! But remember, only a few visitors can enter at the same time.
How much time was spent building the Leaning Tower of Pisa?
Building the Leaning Tower of Pisa? Oh, only a mere 200 years! The building started in 1173 and didn’t finish up until 1399. There were three main construction periods, all broken up by big pauses.
Where’s the Leaning Tower of Pisa located?
Rumor has it that the Leaning Tower of Pisa is in Italy. More specifically, in the city of Pisa, tucked away in the beautiful Tuscany region of Italy.
