@lewisdoherty7621 9 лет назад

I'm not sure how many builder's secrets there would be in the National Cathedral. There are probably volumes of written discussions as to what was planned and how it was to be done, as well as its blueprints. The technology for cathedral construction is well known and documented. I think the major use of such a scanning device would be to the measure the movement of the various parts of the structure to look for possible issues that might be developing. There have been several of the old cathedrals in Europe which were built during the cathedral craze construction era when cities were pushing the limits to outbuild each other, that started to push out of alignment, gaps appeared and they required reinforcing work.

@thelessimportantajmichel287 5 лет назад

There’s often a sizable gap between what’s in a blueprint and the final result because of adjustments on site and because tradespeople sometimes do their own thing. Even in a building as well documented and recent as this one, there’s still probably a lot of new discoveries to be made.

@RenoLaringo 2 года назад

How did they do that? That's the real question, and the answer is simple: ''they'' didn't. All those buildings like cathedrals and so-called ''victorian''architecture spread by the millions throughout the planet are high-tech ''pre-reset'' constructions. ALL our timeline and history is a lie. No one could ever build things like these unless beeing unbelievably technically advanced as well as having highly advanced tools. Just look at the best we can achieve today with high-tech cranes, lasers, electric and pneumatic tools and tons of highly skilled working force... It's obvious.

@77Treasurehunter77 5 лет назад

They should probably go scan all national monuments and historical sites.....Just in case something like the Notre Dame Fire happens to any one of them!

@litogor 5 лет назад

The real secret of the cathedrals is in France because it is in this country that the first Gothic cathedrals were built but the architects left no plans of architecture and no geometrical computation! More than a thousand years ago, the French invented Gothic art without knowing how they learned this method (Egyptians, Assyrians, Babylonians ...?). We know that they used a lot of gold and Pi. The cathedral in this video is much newer and was built with more modern methods and materials! No comparison possible ....

@RenoLaringo 2 года назад

They are all over the planet. France is no more special place than another. They were ALL said to be built in the same period but the narrative about who, when and how is just laughable. This is obviously ancient pre global reset tech (nothing new under the ''sun'') that we know nothing about. Just like pyramids. It's hidden history in plain sight. You might want to look for Jon Levi videos to only name one. Food for thoughts.

They really thought about the name didn't they? Also, why on earth do you have to use a laser scanner on a building built that wasn't finished until 1990? Surely they have detailed plans and blueprints that clearly show the measurements in detail on an engineering and architectural level. This is just much of a muchness - not necessary at all. This building broke ground in 1907 and was finished in 1990.

Odd to talk about mediaeval buildings initially and then spend the rest of the programme looking at a 20th century building. It's also odd to state that the design decisions of the mediaeval master masons are somehow mysterious and unknown, when in fact they are known in great depth. It's first-year-architecture-degree stuff, not some great unknowable mystery.
