Leaning Tower of Pisa is Leaning Less Than Before, Say Experts (theguardian.com) 77

Italy's famously Leaning Tower of Pisa is a little less off-kilter. Nearly two decades after engineers completed consolidation work to keep the tower from toppling over, officials monitoring the monument said recently that its famed tilt had been further reduced by 4 centimeters, or 1.5 inches. From a report: The tower, which has leaned to one side ever since it began to take shape in 1173, has lost 4cm of its tilt over the past two decades, according to a report from the surveillance group that meets every three months to give updates on the monument's condition. "Since restorative work began, the tower is leaning about half a degree less," said Nunziante Squeglia, a geotechnics professor at the University of Pisa who works with the group. "But what counts is the stability of the tower, which is better than initially predicted." The structure, which was badly damaged during the second world war, was closed to the public in 1990 over safety fears and did not reopen for 11 years.

      Awesome news. This is an archaeological treasure and irreplaceable.

      Well, it's a historical treasure, less so an archaeological treasure. In a place where it has been for hundreds of years surround by a city, it's just another old thing.

      But, really, The Slightly Less Leaning Tower of Pisa is a terrible name for a tourist attraction, which I'm pretty sure if the only real function of the tower these days.

        There are very few buildings still standing after ~850 years.

        You could of course ask what is so special about any building - they are just stacked pieces of stone and wood, after all. But after a while they become local landmarks, then regional, then cultural heritage.

        You could also ask what is so special about the Eiffel Tower, or the White House, or the Great Wall of China.

        • There are very few buildings still standing after ~850 years.

          That's a US-centric view. Around the world, there are many buildings that are over ~850 years old. The Leaning Tower isn't even the oldest building in the Field of Miracles.

            First, I'm from Europe. Second, I didn't say that buildings never get that old - but let's be honest, there AREN'T many buildings left that are approaching a thousand years old and are still in such good repair that they get renovated rather than finally torn down.

            • there AREN'T many buildings left that are approaching a thousand years old and are still in such good repair

              Perhaps it's a case of YMMV. I spent some of my childhood living about 1/2 mile from a magnificent cathedral that is about 700-800 years old, along with other churches of a similar age in the same small town, all in good repair.

            You are trolling today aint ya? Chillaxe, my dude.

            Even a gratuitous USA shot - I gotta hand credit where it's due, working that in on a story about the LToP.

            It's an old tower building that has a remarkable history, and while there are other buildings might be older, I think even you would have to admit that there aren't that many that are leaning to that extent - and still surviving.

            • I think even you would have to admit that there aren't that many that are leaning to that extent - and still surviving.

              So you agree with me. It's not the age of the building that makes it interesting and famous, but the lean.

                Its both. It wouldn't be as famous, but the age is interesting as well.

                "So you agree with me. It's not the age of the building that makes it interesting and famous, but the lean."

                If someone identified a building in Detroit built in the 70s that was was now leaning that much, it would be torn down; and nobody would care.

                The lean certainly makes it MORE interesting and elevates it from a world heritage site worth preserving to a world famous landmark; but its definitely not the whole story. It's age and history are a big deal; along with the fact that its been leaning for pretty

      • "Slightly Less leaning", didn't you read? Slightly less is slightly more, at least to some schoolchildren.

          Found the geometry pendant. So if it's upside-down, then it's not leaning at all? :-p

        That's pretty much the only reason it's famous, because it started leaning pretty much upon construction. Otherwise it would be an interesting, but by no means unique historical artifact in Europe.

        Great question. Pisa was the very last thing on my list of things to see in Tuscany because it is a tourist trap. But I went anyway and it was my favorite place. Awesome things about the cathedral at Piza:

        1. Fibonacci is buried there. I turned around and there was his grave. I nearly cried.
        2. The tower is a bell tower. It has very narrow stairs that wind up and down the tower and are made of marble. So many people have climbed the tower that all of the stairs are worn down in the middle from peoples shoes. I would say the middle of the steps has been worn off by 2-3 inches.
        3. The "baptismal" is a third building on the site and is a feat of sound engineering. Every 30 minutes a person will go into the baptismal and "sing a chord". This is possible because a note that is sung in the building echoes around the interior so long it is possible to get three notes out and hear them all interact with each other.
        4. The Italians at Pisa are friendly. That is not true of all Italians in Italy...

        When I was there they had a sort of scaffolding at the base of the tower which was clearly designed to slowly straighten it over many years. I'm glad it worked. I asked if they would straighten it completely and I was told: "That would make it less famous".

        Highly recommended if you ever get the chance to go.

      • I'll tell you what's special: the fucking thing had no guardrails. I wanted my money back but my parents pointed out that I hadn't been the one who'd paid (my dad even had to walk around the outside just to freak me out).

    I had head Italian engineering was unreliable; now I read this. They can't even build stuff that stays unstable reliably!

    • Well, on the plus side, now my uncle will know it will only take another 817 years for Fiat to fix the smoking and randomly-stalling engine and rusted-out floorboards in his X19.

    • I know a contractor who could straighten out the lean in that tower in no time, flat!

  • The martians are starting the tower of Pisa!

    I admit, I'm not architect or mathematician, but offering a measure of tilt in units of length makes no sense to me. Shouldn't the units be in degrees? Otherwise, at what point on the building has it lost 4cm of tilt? 1cm off the ground? 1m? 10m? At the very top?

    From TFA: "It is half a degree straighter after restorative work".

    • Actually a depressingly large number of construction/carpentry/HVAC people. Theyâ(TM)re always talking about a half inch of slope (in a deck) or somewhat.

      In fact, the reason we had to be sure to use âoeCelsiusâ rather than the older âoecentigradeâ is because the civil engineering crowd already used the latter for a unit of slope â" calculated as rise over run times 100, IIRC.

          Because Slashcode is a steaming pile of shit. It's basically at the same level of quality as the competence of the so-called "editors."

      • Slope makes more sense in many things than angles-- it is much easier to measure and mark directly with common tools when you are looking at small angles.

        It is also helpful when thinking in physics terms without worrying about the trigonometry.

    • Because the degrees are microscopic, but rise over run is a reasonable, understandable metric.

      If the article had simply stated that it had moved .00825 degrees towards vertical we the audience would of needed ten minutes of mathematical calculations to figure out what that meant. But instead of needlessly trying to confuse people to try and make themselves seem like experts to try and justify some unimaginable salary, they provided the correct units.

  • There's 33 comments and nothing on this, so here I go...

    Did the Tower of Pisa see a sexy girl?

  • degrees = tan ( x / y )
    arctan (deg) = x / y
    y = x / arctan (deg)
    y = 4 cm / arctan (0.5 deg)
    y = 458 cm

    The leaning tower of Pisa is just 4.6 meters tall?
  • Remember, Pisa's tower is banana-shaped and thus needs to be leaning.

    Otherwise it will collapse.

  • I see nothing, in any of the links to the Tower of Pisa, that even hint of it being damaged during WW II. It was in danger, no question, given bombing in the city, and the well-known incident of an American Army artillery spotter deciding not to bring fire on it when it was (maybe) being used as a German observation post.

    But no damaqe.
