Analyzing the North Face Corridor of the Great Pyramid

The ScanPyramids Mission revealed to the world on March 2, 2023 the first images taken from inside a hidden corridor within the Great Pyramid of Giza.

The hidden North Face Corridor of the pyramid was found to contain a gabled ceiling, known as a saddle vault. This design redirects the weight of the pyramid from above, and thus it was widely assumed to be a so-called ‘weight-relieving chamber’ protecting the descending corridor below.

But many details about the North Face Corridor suggest that protecting structures below may not have been its primary purpose. This video compares the design to other saddle-vaults and puts the corridor in context to the other features within the Great Pyramid.

I like how Hawass was totally against the scan pyramid project, and he’s in a photo with the team taking credit. That guy is the gatekeeper of knowledge in that country and really should be challenged in every aspect.

[GIANTENEMYBRD]

This channel is a great example of why having logical outsiders challenging status quo can be so valuable. I believe there is something to be said for looking at things with fresh eyes. Great video.

My first thought was, “how long until this episode’s dig at Zahi Hawass?” Under a minute. Not disappointed in the slightest. It’s a certified staple of HfG. Brings me joy every single time 😄

It's a breath of fresh air to find a channel that isn't sensationalising these type of discoveries.
You keep an open mind while leaning toward the evidence. Kudos to you my friend.

Channels like this one are why I love YouTube. Gems like this channel, made by someone passionate about the content and subject matter they create, who build upon the work done in the field up to that point and truly add value in terms of analysis, hypothesis formulation, debate and nuanced commentary, are such a gift. Justice should demand that someone such as yourself should have a documentary crew and a production budget behind them with which to make cinematic and high-value production style content for mass broadcast to as wide an audience as possible, and yet it is here, for free, affording the creator minimal financial reward despite all of the effort put in, and is available to those of us interested and lucky enough to find it on a platform such as this. Thanks for your passion and knowledge, mate. Cheers, Matt

A basic tool of hard rock mining is a "tattle-tale". This is a wooden beam placed between two notches that hold it in place. A miner can wiggle the wood so he knows its feel. If the the beam starts to feel looser or tighter the miner can know if the rock is shifting. Clear "tattle-tale" notches appear across from one another high in the ceiling of the Northern chamber in the Bent Pyramid across from the dug passage connecting to the western corridor. The ancient Egyptians were testing if their designs worked. They wanted to know if there was any subsistence or shifting in their structures. The shallow holes dug into the gabled ceiling of the new passage could have held "tattle-tales". Same for Campbell's chamber.

Ah, the most expected notification of the week. Love your videos specially the detailed diagrams, Mr. Granite

[skelta]

A big Thankyou to you and Ancient Architects for the work and research your channels put out to help understand these significant finds.

[KlausJepps]

I want to express my appreciation for History for Granite's fresh take on the pyramids and his enthusiasm for exploring them further. History is a never-ending journey of discovery, and there's always more to learn and explore. Thank you, and I hope to see you again soon for another exciting adventure.

[InfamousTog]

I can't stop recommending this channel to everyone I know when videos with this quality keep coming out.

[gotMylky]

I feel like watching your videos is as close to - being a pioneering explorer to find new land - that I will ever get. Such fantastic analysis I love your work so much <3

[methylmike]

history for granite notifications are producing huge amounts of dopamine.
you are a hot second away from "drop everything im doing" status

awesome!

[jamesrobb]

Thank you for all the meticulous research and amazing presentations you provide

[xtopherxy]

Wow. I've binged every single one of your videos this weekend! I'm now more interested than ever!

[Gin-toki]

Interresting video.
Zahi and his gatekeeping aswell as the general withholding of information about the pyramids is what made me loose my overall interrest in the pyramids and egyptology as a whole. I was really into it as a child and teen but the frustration became too much.
I'm glad there are people who genuinely try to share knowledge and information about this topic, it is afterall a heritage of the world and should be shared with us all equally.

[lightdot]

I've been waiting on this to drop since the morning they announced the discovery lol

[douginorlando]

Here’s a new perspective … consider when the pyramid was half built. The new corridor’s raised floor is the same level of blocks as the floor of the queen’s chamber. The architect would have walked around on that layer and surveyed the floor plan (kinda like walking around a partly built house with the floor but no walls installed yet). I bet that was a major milestone … and extra effort was made at that point to level the floor and correct/adjust for any deviations outside established tolerances.
And the next 3 layers were special, with walls for chambers and corridors, then chevrons for ceilings. There may be other special things planned for that layer of the pyramid

[Punchcado]

I've seen a couple of other early treatments of this subject and yours is of course the most informative. Thanks for this. I always look forward to your thoughtful, scientifically-supported videos and am glad to see the channel growing.

[wishgodgirl]

Ran out of new episodes to watch, starting to watch them a second time! This is fast becoming my favorite channel. Your simply going to have to make them faster! Lol. Keep up the wonderful work!

[mattking]

Jean Pierre Houdin has the best explanation of the construction that has ever been put forward. Great to hear him mentioned 👏
