The lean isn’t just a fascinating oddity; it is integral to the historical character of the tower. It’s a big part of why we care. Unlike the millions of photos of tourists pretending to hold the Pisa tower up, the contractors, restoration experts, and engineers actually did it (for the next few centuries, at least).

Kind of silly to insist on keeping the tilt and risk the entire tower just to keep a tourist trap.
i m italian and this is a fake news
I don’t think they want to leave the tower leaning because of history, but more so because its curved so it would still be crooked at the top regardless of the foundation.
and thats how the pizza tower was born
The soil can only hold 7% more but they loaded one side with 600 tons of lead weight.. really pushing it to the limit
I visited Pisa with my family in the mid-1970s when it was still possible to climb to the top of the bell tower. When we got up there, we found a Japanese tourist had folded up a paper airplane and sailed it off the edge while we watched, lol. I have to say at the time it felt like sacrilege, but now it’s a fun memory.😂
But if they left it at 5.5º, doesn't it still only have a factor of safety of 1.07, ie, isn't something like an earthquake going to tip it.
A superb video, I recall an excellent and longer, more detailed documentary on BBC back when this was all being worked on which blew me away somewhat.
I rather like the generations of original builders correcting the lean by building it wonky in the other direction, if only they’d known that if later generations were to straighten it, it would look bent in he other direction.
We were there in 2009 during a 2 week med cruise. Incredible sight and history seeing it for real. Shalom
I guess its now the Upright Tower of Pisa
I thought I saw this video, but it was worth seeing again. Seems like they should have gone for at least one more degree.
Of course nobody wants a Straight Tower of Pizza…
1:26 My friend’s friend’s Naughbor’s dog isn’t
One of the coolest restoration projects of our time. Make the Tower of Pisa stable without changing what people love about it. Mission accomplished! 😊
1/2 a degree. billions spent
I need a Kosher mommy drink on the rocks!!! Make it a double shot!!
This is why you need to use Sanzari construction.
When someone starts saying 1-2 million years you know they're full of 💩. The tower of Pisa existed before the great flood. The flood waters pushed it in its lean. The fact that not even modern buildings can hold together like the Pisa tower at that lean is a testament its construction is superior to what we have.
Foolish opening comment , ‘millions of years ago’ There is zero evidence in science for deep time and the religious philosophy of evolutionism. So don’t make it part of your narration, I come here for science not pseudoscience
from now on i will refere to this building as the "Curved Tower of Pisa"
engineers didn't "straighten" the tower, they stabilized it and reduced the tilt from 5 to 3.5 degrees. if it was straightened it wouldn't be called the leaning tower of pisa any more would it
Should paint it yellow since it's bent like a banana
Only here can a enganeering blunder still exist , anywhere else they would have just rebuilt it ….lets save a screw up ……dumb in my opinion…..
I just realized something. Why doesn't the Millennium tower in San Francisco try something like this to try and fix their own leaning building? I'm not an engineer but I figure something of similar lean can use a similar method to fix it slowly over time.
