Ancient Technology: Great Pyramid Portcullis Antechamber EXPLAINED | Ancient Architects

Of all the videos I’ve made over the years on the Great Pyramid of Egypt, I’ve never made one on the Antechamber, the small room that you pass through from the Grand Gallery, before entering the granite-lined King’s Chamber.

It’s called the 'Antechamber' but a better name is the 'Portcullis Chamber' because the small space is a security feature. It's function was securing the contents of the King's Chamber and it once housed three granite portcullis blocks.

Researcher Keith Hamilton has just recently published two detailed guides on the Great Pyramid and I have used his work as a basis for this video because, as many of you will know, with regards to researching Ancient Egypt, Hamilton leaves no stone unturned.

This is a somewhat strange, rough and ready chamber of the Great Pyramid of Egypt and it has attracted a lot of attention in recent years because of a boss or 'nub', found on the back of the upper granite leaf block.

Watch this video to find out all about this chamber, how it may have worked, if it was successful and also why they included a boss or nub inside.

Always a pleasure to see this topic covered! If I reach 100k subs I will do my best to explain the portcullis functionality, and Egypt's Old Kingdom history may never be the same.

You diagrams, arrows, labels etc are AMAZING. THANK YOU for taking the extra time to properly label every details that the audio references. Well done

The wooden rollers are the smoking gun here. It shows that the Great Pyramid did incorporate functional machinery and must have had some practical use.

Most people don't understand how much that ante-chamber area has been re-worked and changed in modern times. Dynamite, chiseling, etc.

I’ve been waiting for someone to explain this topic for years

Nice to see the nubs mentioned.. the portculis nub has been documented many times on my own and Andrew's channel also very reminiscent of the nubs found in peru.. the Athens acropolis.. ect.. the menkurae pyramid has many of them aswell infact so does the osirion and multiple other sites aswell.. Adrian is an excellent researcher pleasure to have him on the team. Thanks for the nub mention here maybe nubs of egypt next matt ? All the best Phil aav

How could I have not heard of the antechamber before. Thank you.

[StephiSensei]

As always, brilliant analysis with a pinch of humility. Bravo!

[AncientAdvancedCiv]

"clearly made to allow ropes to pass"... regurgitating this loose theory delivered with an air of certainty. Keep the illusion of our comprehension of the Great Pyramid alive. Love your work.

[bradschoeck]

Been wanting a more in depth video about this for a long time. One of the most interesting design aspects of the pyramid.

[ReinhardvonHolst]

To me it raises more questions than answers. Nice work again, Matt. Peace from Berkshire.

Now, that’s how you lock the door, well, except form that inside job crew. Fascinating and thank you.

I enjoy all of Ancient Architects videos

Excellent explanation of the ceiling damage to the entrance corridor into the chamber. Having explored it myself, it was a great curiosity, not to mention how confining and small and tunnel-like the corridor was, so you had to crouch to use it, then opening up into the huge King’s chamber. Which all seemed very odd to me.

Amazing stuff! Thank you Matt!
I remember years ago watching a YT video of a guy making a wooden model of the porticullis...including how the Egyptians would have thought about it, including the two different sides where the wooden beams went...one side rounded, the other flat...but of course, cannot find it now...

[samuelallott]

I absolutely LOVE your videos! I've been waiting for you to cover this subject like a child on Christmas Eve! Thank you so much!!

Hi Matt, that leaf boss reminds me of protuberances recognized around the world in many polygonal constructions of ancient chronology.

[bomma]

My first time hearing of this mechanism. Thanks!

This is like the ultimate news network, Breaking news for 15, 000 years ago. LOL I love this channel
