Two Entrances to the King’s Chamber and How They Were Sealed—More With Jean-Pierre Houdin

Is there a second, as of yet unopened, entrance to the King’s Chamber in the Great Pyramid?  How did the ancient builders seal the burial chamber?  Measuring the entrance that we do know about suggests that the sealing block would have fit into the entrance like a cork, but this cork was made to plug the neck from within the bottle.  In other words, the sealing block could only have been closed from within the King’s Chamber. 

So who pushed the block into place, when did they do it, and how did they get out?  Human sacrifice within royal tombs had not been practiced since the early years of the Second Dynasty, so, cork or no cork, ultimately the King’s Chamber had to be sealed from the outside.  How do we reconcile this contradiction?

This is the fourth in a series of articles and interviews conducted by Marc Chartier, writer and webmaster of the French-language site Pyramidales, with Jean-Pierre and other key members of Team Khufu, provided in English exclusively to Em Hotep.

 

The King’s Chamber in its current state

In the new “reading” that the architect-researcher Jean-Pierre Houdin is suggesting for the pyramid of Khufu – Khufu Reborn – the King’s Chamber takes all the honors. And for good reason! This room is in fact the heart of the entire architectural system of the monument, its function and that of the entire pyramid being to contain the mummified mortal remains of the king who built it, for eternity.

Well, the funereal chamber of the Great Pyramid has been, and still is, the subject of a great many interpretations and endless, sometimes stormy debates, regarding its purpose, its structure, its superstructure (what are known as the “relieving” chambers), its shafts (for “ventilation”), the damage it has suffered (well known cracks in the ceiling, which have given the neighbors something to talk about), its final use (did it or did it not house the august pharaonic mummy?), its hypothetical counterpart lost who knows where in the bulk of the monument (did someone say “secret chamber”?), etc.

To the list of questions and answers, we must now add the entrance to this chamber, namely the only passage still “in service” today, under which visitors must “bow their heads” in order to enter the chamber, in the north-east corner. For centuries and centuries, the “Consensus Thinking”, to use Jean-Pierre Houdin’s expression, has taken this entrance to be the one used by the funeral procession transporting the mortal remains of the Pharaoh.

In Khufu Reborn, Jean-Pierre Houdin takes this entrance to be in reality merely an additional element in the service circuit, therefore already sealed long before the day of the royal funeral. According to his analysis of the pyramid, the King’s Chamber had to be accessible through another – “real” – entrance, the end for the “Noble Circuit”, now hidden from our eyes.

Actually, not everyone’s eyes! As the following demonstrates…

    

Reading the Language of the Stones

At a glance, the King’s Chamber at its heart bears witness to the changes or upheavals the Great Pyramid of Giza has undergone over the centuries (sarcophagus lid missing, damage in the north-west corner, etc.), the various intruders, well intentioned or otherwise, not always having had the wherewithal to achieve their ends.

A more experienced eye will be able not only to interpret these changes, but also to recognize the original plan in the construction and lay-out of the chamber. Stones have their own language for those who can understand them.

     

First Observation: the disappearing block

The first observation made by Jean-Pierre Houdin: where did the stone block come from that we could still see, a few years ago, beside the sarcophagus, on the west side of the north wall of the King’s Chamber? And what happened to it, since it has now disappeared?

Entrance in the northeastern side of the King Chamber

The answer to the second part of the question is simple: during renovation of the King’s Chamber in 1998, Dr Zahi Hawass, then supervisor in charge of Egyptian antiquities, ordered the block to be removed. No doubt he thought it was too untidy.

“At the same time,” comments Jean-Pierre Houdin, “he removed ‘part of the puzzle’.”

“Happily,” the architect continues, “many witnesses had made drawings and taken photographs to prove the existence of this block.” But as to where it is now… mystery!

More importantly: what was the original position of this block, and what was its function in the overall structure?   

The block’s dimensions, observes Jean-Pierre Houdin, exactly matched (since it has disappeared, we should use the past tense) those of the entrance in the east of the funeral chamber’s north wall. So it quite naturally had its place, as originally planned. 

We should immediately note that there is a difference of 2 cm between the floor levels in the chamber and in the corridor, the latter being lower. We must also be aware that the cross-sectional area of the corridor between the Grand Gallery and the portcullis chamber is smaller than that of the corridor between the portcullis chamber and the King’s Chamber. So for Jean-Pierre Houdin, the conclusion is clear:

The block that sealed the entrance to the King’s Chamber, on the east side, never passed through the portcullis chamber. And yet, it finished by exactly blocking access along the line of the north wall of the King’s Chamber, pushed up against the floor in this room. For this reason, thieves who succeeded in reaching the back of this block via the entrance dug in the north face of the pyramid, the ascending corridor, then the Grand Gallery and finally through the portcullis chamber, were forced to break the top part of it and, when there was enough room, to tip it into the King’s Chamber, where it loitered for 1,250 years.

Northeastern entrance: to bow one’s head

In other words, this block, whose function was to block the north-east entrance to the King’s Chamber, was not put in place “after” the royal funeral ceremony. “It was from the 17th year of the pyramid’s construction, a date mentioned by graffiti in the last ‘relieving chamber’,” explains Jean-Pierre Houdin:

…so when construction of the King’s Chamber was finished and the counterweight system in the Grand Gallery no longer served any purpose, that, pushed from the inside of the chamber before the setting in place of the slab on which it stopped, it was put into the place it occupied until the year 850 AD (arrival of Al-Ma’mun), to seal access to the chamber. It was thus sealed for 3,350 years, no more, no less, until the day Al-Ma’mun’s advance scouts broke it and then tipped it into the chamber. But it was then no longer in its original position.

It follows that the migrant block, even if it was observed for a long time close to the grille covering the tunnel in the north-west corner of the King’s Chamber, had nothing to do with this tunnel opened by Al-Ma’mun and later re-visited by Perring. It did not come out of it. It was actually made of granite, while the sapping opens onto limestone blocks. Note that I am using the past tense in my description of the block, as it is no longer accessible for observation following the strange decision by the ‘master of the house’ to remove it from our view!

       

Second Observation: a second entrance, “between the lines” in the north wall of the King’s Chamber

It becomes a question of the sapping, on the west side of the north wall of the King’s Chamber. It has a quite unusual history.

Why did Al-Ma’mun’s soldier-engineers dig here precisely? They must certainly have spotted clues “somewhere” in the wall, attracting their curiosity and justifying their efforts.

These clues, if they were really revealing, should still exist today. Al-Ma’mun, doubtlessly searching for any treasure associated with the funereal chamber, simply made a mistake in interpreting them. He had excavations made downwards, when he should have dug horizontally!

So let’s look at the north wall, following Jean-Pierre Houdin’s instructions:

What do we see on the wall? On the right (east side, low down, in orange), the entrance through which we currently enter this room. On the left, the layout of granite blocks forms a doorway (in pink) that takes the entire weight of the (dark) granite ceiling beams. The (yellow) blocks filling the doorway do not bear on the central block at the bottom (blue). This seals the second entrance. It is free, exactly like the block that once sealed the first entrance. Free: in other words, it could be moved… for example, at the end of the king’s funeral ceremony, when the pyramid had to be sealed.

The cracks on the North wall of the King’s Chamber (from Gilles Dormion drawings)

Since these observations I have entered the pyramid numerous times, especially to the King’s Chamber, to make a close analysis of this north wall. I then paid attention to several other details. The first yellow block above the blue block is cracked in two places, at the center. This proves that there was a space between the two blocks, so that the one above did not rest on the one below.

Furthermore, we know that the ceiling beams have been cracked since construction, following subsidence of the chamber’s south wall. Later, certainly when Al-Ma’mouns workers dug the hole at the foot of the second entrance, the north wall also moved a little, 2 or 3 mm, i.e. practically nothing. But this was enough for the yellow block to crack and rest on the blue block.

The true entrance in the King’s Chamber

I also carried out an experiment with an out-of-date plastic credit card: I tried to slide it into the right-hand joint between the blue block and the pink block of the doorway I could do it easily, although it is practically impossible elsewhere. (It is often said of the joints in the pyramid that they are so perfect you could not insert a razor blade into them.) I slid this card, laid flat, along the stones, from block to block, to check their alignment. The only time my card stopped was exactly on this joint, proving that the blue block is slightly below the pink block. If the blue block had been put into position at the same time as the other blocks in the chamber, it would have been perfectly aligned with the others.

     

We close!

At this stage in the inventory of structures in the Great Pyramid, as made by Jean-Pierre Houdin, we find the subject of the previous article in this series, concerning this author:  the two antechambers. It is also good to remember certain developments from the second part of the exclusive interview given by the author to Pyramidales (see under the sub-title “A complex and wonderful closure system”).

Passing (virtually) through the north wall of this room, from inside the King’s Chamber, on the other side we actually find the upper part of the second antechamber, by passing along a fairly short corridor that plays an essential role in permanently sealing the funereal chamber, after the royal funeral.

Finally, do we really need to insist, in order to pay homage to a preconceived and outdated idea that found favor for a while? The King’s Chamber was not permanently closed from the inside. The royal mummy could hardly make workers, however devoted, wall themselves up like kamikazes. While the stone blocking the first entrance – service entrance, east side – was positioned from inside the chamber in the manner and for the reasons given above, that blocking the second entrance – the “Noble Circuit”, west side – was positioned from the outside by means of a pushing-block and piston operated from the second antechamber.

This technique introduced by Jean-Pierre Houdin in his reconstruction of the building of the Great Pyramid has been described and illustrated in the interview mentioned above.

Given its complexity, here is another explanation of it, a Pyramidales special, offered by the author:

      

The problem:

1 – For the day of the royal funeral, the corridor between the second antechamber and the King’s Chamber had to be totally cleared to allow the funeral cortège to pass.

2 – Yet it had to be possible to close the King’s Chamber with a granite block that sealed it perfectly, so having dimensions 2 or 3 mm smaller than its final position, and stored “nearby, on hand”.

3 – The King’s Chamber had to be closed from the outside, so that the workers were not imprisoned in the room after the operation, with no possible way out.

4 – It is impossible, “practically” and “materially”, to store the closure block in the second antechamber, then to raise it 7 m and present it in front of a passageway having the same dimensions, to the nearest 2 or 3 mm, and insert it … This would have required equipment and precision of movement that the Egyptian workers performing the operation could not possibly have provided.

5 – The “storage” area for the closure block therefore had to be located between the King’s chamber and the second antechamber, at that level.

     

The solution:

1 – Presence of a small corridor, about 4 cubits long and 2 wide, perpendicular to the connecting corridor and on its east side

2 – In this small corridor, two “twin” blocks (1 and 2 on the diagram above) were placed, the first becoming part of the east wall to the connecting corridor, the second “stuck” behind it.

3 – The front face of the second in contact with the rear face of the first was very slightly concave so as to leave a small space over the greater part of the surface. A brass “pad” was inserted into the second block, two thirds of the way up, projecting sufficiently to be theoretically in vertical alignment with the face. Its role was to allow the first block to be pushed fully into the corridor without “jamming” it against the opposite wall. When pushed by the piston (4 on the diagram), only this pad would be rubbed and very quickly worn away by the granite of the first block.

4 – As the driving force for the system, a pushing block (3 on the diagram), based on the type of drop-stone trap built into a corridor of the Bent Pyramid: this expertise gave rise to a pushing block used for the Red Pyramid and Khufu’s Pyramid.

5 – Up to this stage, everything was done “automatically”, the system being triggered (removal of a wedge across the corridor) by workers further on, movement being achieved on a “layer” of very fine sand.

6 – A stop prevented the pushing block from going further in its movement than necessary. When the second block had taken the place of the first, it could no longer move forward because the pushing block was at the end of its travel.

7 – The piston was pre-assembled in the second antechamber, on cross-beams. It did not move as long as the first block had not been pushed into the connecting corridor.

8 – Once the block was in the corridor, the piston was moved up to its north rear face (formerly the north side face of the block when it was still in the perpendicular corridor), then placed against it.

9 – In order to get the 750Kg-f needed to move the block, eight workers climbed onto the traction ropes, and four others pulled on the assembly: the first block moved forward in the connecting corridor until it stopped against the raised edge of the King’s Chamber floor.

10 – At the end of the operation, everything that could be recovered was dismantled and removed.

     

Much more to come!

A new article that directly answers one of my questions from the previous articles, outstanding! Now I have more! Please don’t take them the wrong way; I am in awe of Jean-Pierre Houdin! When sealed, the ‘known’ entrance would provide a smooth, finished wall but I really don’t see why it would exist at all in this theory. With the ‘noble circuit’ entrance (that was engineered from the start in theory) why would there be two entrances to the burial chamber? Another way to say it is, “if it was going to be sealed up in year 17, why does it exist at all”? During construction, the chamber would be accessible from above (until the ceiling was in place) while the grand gallery continued to function in its proposed role as counter weight helping lift in more beams and rafters. If workers needed to enter the chamber they could enter through the ‘noble circuit’ entrance.
“We must also be aware that the cross-sectional area of the corridor between the Grand Gallery and the portcullis chamber is smaller than that of the corridor between the portcullis chamber and the King’s Chamber.” It is clear that the sealing block was not brought in, but what prevents it from being simply staged in the portcullis chamber…then being pushed into place sealing the kings chamber…then lowering the blocking stones.
“Happily,” the architect continues, “many witnesses had made drawings and taken photographs to prove the existence of this block.” But as to where it is now… mystery!” This implies that Jean-Pierre has requested to see the block….and been given the run around. True? I shudder to think, but I would speculate that it was broken up in order to remove it.
Just for a bit of fun, I notice that the west wall appears to have a blocking arrangement that is very similar to the ‘known’ entrance (from your article picture)! The block above the stone has a stress crack (repaired) as if weight were now being transferred to the block below when originally there was none. The northern most seam tolerance does not appear as close as other stones. The Bent Pyramid had a western entrance (though to a different chamber). Has Jean-Pierre looked at or considered this?

Very interesting observations!

Do you think block 1 would ever be removed? It appears that it would not open a very practical everyday acces to the antechambers due to the difference in rooms heights, and it would probably require cutting the block (Then the good Dr. would have another one to haul away!)

Would it be more reasonable to gain access to the antechambers from the lower side and just leave the corridor to the KC blocked?

Hi Rico,

I am so sorry I took so long to write a response to your question! Please be assured that I always enjoy your comments and questions, and somehow this one was overlooked. I have been doing some maintenance on Em Hotep today and noticed that there are some unaddressed questions and comments, and even some that were accidentally caught in the spam filter and have been in Limbo for months! And as there are more pieces of spam than I can possibly dig through—literally thousands—I am sure I will not catch all of them. You can believe that I am checking the spam que regularly now!

So for your observations and concerns, I think that the first logical step is to do the non-invasive surveying that would confirm the existence of the chambers and passageways, as well as their layout. Once we know what we are dealing with, Jean-Pierre and the Project Khufu team would be able to make a more educated proposal to the SCA for how to proceed. Laval University already has the people, equipment, and plan for this, now it is a matter of securing all the permits to continue with the work. The situation in Egypt at the moment has not just changed the pieces on the board, in many ways it has changed the rules of the game. But everyone remains confident!

As for pulling out blocks, that might be a tricky case to make! Surely proof of the existence of the antechambers and the internal ramps would make it worthwhile to open these chambers up in a minimally invasive way, especially since their continued closure pretty much assures there will be artifacts of some variety still within. Maybe even… well, I’ll leave it unsaid. Dare to dream! ;-)

But even if the Laval mission can simply prove that there are hollow spaces behind block 1 or elsewhere, the Djedi Project has proven that we have the tools and technology to drill into and explore these places with very little (practically none) risk of damaging the pyramid or even significantly scarring it. Scoutek and the Leeds robotic team have proven that they can use miniature crawler and snake cameras to go where nobody has been before, at least nobody in 4,500 years!

Methinks Khufu’s Pyramid has not seen its last endoscopy!

has anyone noticed that the block was left infront of the wall, so that no one could get to the second entrance, or was it used as a step to stand on to cut or push into the wall. its just a long way to move a big block from original place

the second thing is the lid to the box is no where to be seen, that is because it is in the second room behind the wall, it was used, just like the block that was moved

This theory of internal ramp and antechambers are very interesting. I have been thinking of hidden rooms and nobody has yet recovered the real treasure of kufu since my childhood. I have read about the Theory of Mr JP houdin but I couldnt see any explanation about the narrow shafts in any place.. Do you or does he have an explanation about the shafts?

Hi Mehmet,

Thank you for reading Em Hotep and taking the time to write :-)

Jean-Pierre’s theory is that the shafts coming from the Queen’s Chamber were used for communication during construction, and that the shafts coming from the King’s Chamber were primarily for ventilation.

You can read more about the shafts here at Em Hotep with these articles:

Cheers!

I was thinking that the logical place for the large block that has gone missing was that Hawas may have put it down into the pit Al-Ma’mun dug under the floor behind the sarcophagus.

I also have an idea that the “ventilation shafts” may have been channels for ropes for some reason, perhaps to act as a telegraph of some sort, or to be used as some method to activate a lever or pulley system used at some point.

Fascinating info on the “true entrance”

My question is – Can the horizontal tunnel in the subterranean chamber not be a dead end? Can the same method of looking at the placement of stones allude to another chamber or shaft at the end of the tunnel? Maybe it has a similar stacking configuration to take the weight off a lower stone that may be removed?

I really hope they complete this exploration during my life-time. I have been fascinated by ancient Egypt for nearly 50 years. Jean-Pierre’s theory is the most plausible and feasible I have ever seen about how human beings built this thing with the technology and tools of the time.
No need for aliens, anti-gravity, Atlantis or Annukacki!

Hello there.

Yours is an utterly fascinating read. I watched the video first time this morning about M. Houdin, and now it’s 3pm and I’m still reading this webpage after being directed here by him on a forum.

I lived in Egypt from ’93 to ’99 and saw the pyramids nearly every day whilst riding my horses. They changed their look depending on the time of day and weather and were always stunning.

Whilst I was reading about the construction of the pyramid a thought occurred to me: Where, in your graphics on this website, was the inner construction tunnel shown? It’s not mentioned at all! Mr Houdin’s explanation is that they had used it to finish the upper 3rd of the pyramid and they would already have had to start to build it into the base to gain access from the base to the top (which is how it’s shown in the graphics in the original video).

Soo…I’m writing to say that methinks your static graphics and descriptions might need some tweaking to match up the information! ;)

Best regards,
Diana Kisi (currently in Melbourne Australia)

In adition to my above post:

It is possible that all these early kings decided to be buried elsewhere. J.P. Lepre in particular presents a compelling argument that all early kings had two burial edifices, one in the north and one in the south, to represent the duality of their reign over both Upper and Lower Egypt. On this basis he suggests that the reason that so many coffers have been found empty, even when sealed, is that the pyramids in which they were found may have been merely cenotaphs connected with ritual practices

great article

I am a fan of Jean-Pierre Houdin’s great intuitive insights.

I am glad we agree that 28 blocks were used in the north wall. (including the one to seal the chamber)

to the author of this article could you please help me out with the south wall count….?

I am trying to get a count for the south wall and unless I go count the blocks myself, I will need to rely on somebody like yourself who has been in the chamber recently.

from my current sketches etc. I have anywhere from 35, 36, or 37 blocks used in the south wall from the various sources on the internet.

Do you have a sketch that confirms any of those numbers 35, 36, 37?

much appreciated

p.s.

could you tell me how many blocks where used on each course in your final tally.

i.e. the problems creating a different total count seem to arise with the first three courses, cracks are counted as two blocks etc.

an accurate count would be grand.
thanks again
