B - The Real Entrance of Cheops Pyramid

Units: The royal cubit (Mahe), further on named cubit:
1 (royal) cubit [Mahe] = 52.36 cm = 20.615 inch ==> 1 cubit = 7 (hand)palms.
1 palm = 52.36 cm / 7 = 7.48 cm = 2.945 inch ==> 1 palm = 4 digits (finger widths)
1 digit = 7.48 cm / 4 = 1,87 cm = 0,73625 inch


All, literally all corridors and rooms that are currently known in the Cheops pyramid are nothing more than technical shafts or rooms. The really important rooms in the pyramid have remained untouched throughout the centuries. The coffins and/or sarcophagi of the so called gods and their written history are still there.

Where exactly are those rooms located?

In order to reach those secret rooms, we must first try to unseal the entrance. This is here, of course, about the real entrance to the pyramid and not about the tunnel that the workmen of caliph Al-Mamoen have carved into the pyramid.

Wikipedia: “Shortly before his death, during a visit to Egypt in 832, the caliph ordered the breaching of the Great Pyramid of Giza looking for knowledge and treasure. He entered the pyramid by carving out a tunnel into the Great Pyramid near where tradition located the original entrance. The resulting passage, which was later named the "Robbers' Tunnel" is the path along which tourists enter the pyramid today”.

Ch 6. Outside of Great Pyramid - Sec 32. Original position of the entrance.

Book online see:

Originally, the entrance to the pyramid was hidden behind a large limestone trap door. From the outside there was nothing to be seen, if one knew perfectly where that trap door was located, it could be lifted quite easily because it was almost perfectly balanced. Perhaps only one individual was needed to open that trap door, only a small imbalance caused that limestone trap door to close or stay closed.

The real entrance to Cheops pyramid.
The rotating mantle stone as well as
the surrounding stone blocks have since long disappeared.

The perpendicular cross-section of the descending
(technical) shaft measures 2 by 2 cubit.
The large stone blocks above it cover an area of ​​at least 6 by 6 cubit.

No, this is certainly not about the 2 by 2 cubit descending shaft that goes down at an angle of 26°. As already mentioned, this is a purely technical shaft. The real entrance is at some distance above it, just below the double enormous roof beams.

[1] The descending shaft (2 by 2 cubit) was already known in Greek antiquity and investigated over its entire length. For example, the Greco-Roman geographer Strabo gave a clear description of the large underground chamber on which this shaft ended (185 meters below the top of the pyramid). "Graffiti" was also found from the time of the Roman occupation, a confirmation of regular visits. "

[2] In his Geographica, written about the beginning of the Christian era, Strabo states that the great pyramid "slightly up on one side, contains a stone that can be removed and thus shows a sloping passage to the foundations" .

At the time of Strabo the real entrance was already known as well as the descending shaft that led to the large underground chamber. Two other shafts, starting from this underground corridor, weren't yet discovered at that time.

Apparently that entrance was again forgotten, it seems that at the time of Al-Ma'moen one no longer knew where the real entrance was.

Under the double roof beams are huge limestone blocks behind which the real entrance is hidden. These stone blocks cover an area of at least 6 by 6 cubit, a passage behind it of 4 cubit wide and 5 to 6 cubit high is certainly possible here. Removing those visible large stones will certainly not be easy, but with this alone the problem is still far from being solved.

Behind these visible limestone blocks is an even larger monolith,
probably a granite sealing block which was pushed from the inside to

the outside and pressed into the surrounding walls.

This enormous monolith, the sealing block of the real entrance, was at least at the top (visible) provided with tongues and grooves. The teeth on this monolith fit into the grooves (and vice versa) of the blocks above it which belong to the massive part of the pyramid. They did fit together perfectly when closing the pyramid. The tongues and grooves ensured perfect guidance and positioning of the monolith, so it moved exactly like the builders intended. This monolith is probably very tightly positioned, it will almost be impossible to remove him and going around the stone won't be easy either.

Tongue and groove, here in 2 wooden beams,
makes perfect positioning possible.

From the entrance, behind the sealing block, there will be a secret passage.
This time, the ascending passage will have decent dimensions
with a width of around 4 cubit and a height of 5 to 6 cubit.
The floor of it will now have steps, shall form an easy staircase.

Entering into that secret passage will therefore not be easy.
That monolith (sealing block) was pressed into the entrance,
removing it will certainly not be easy.

This yet undiscovered ascending passage will probably end at a wall, by chance we know that behind that wall are the construction rooms above the King’s Chamber and consist of huge granite slabs. It is to be expected that the side walls, the ceiling as well as the wall at the end of that passage will be totally bare, there won't be any reliefs in the walls there.The only thing that could stand out is possibly a staircase, this is something that does not occur anywhere else in the pyramid. The ascending and descending shafts, with a slope of 26 degrees, don't have any step and are smooth. It's therefore very difficult to climb or descend these shafts, but these are only technical shafts, for the real entrance one would expect at least a staircase.

B10 – Top view of the King’s Chamber.
The earlier erroneous assumption that there was a corridor
or a room right at or in the center point of the pyramid [M].

It has been assumed for a long time here that in the exact center point of the pyramid there would be a room that was the starting point of a corridor towards the true secret chambers in the pyramid. In retrospect, this was obviously a wrong idea, between the corridor to the King’s Chamber and the one towards the center of the pyramid there would have been at most 9 cubit limestone and this is of course far too little. The granite walls in the King’s Chamber couldn’t offer any protection in this arrangement. The passage through the King’s Chamber or the construction rooms above it could be canceled out in a way that was too easy, this by simply chopping a hole from one corridor to the other.

B10b - A corridor [C] going towards the real important rooms in the Pyramid.

In reality, it’s more likely that there's a corridor [C] behind the westside of the constructions rooms, a corridor which is going straight forward towards the most secret rooms much further westwards in the pyramid. In this case it would be very difficult if not impossible to reach this corridor.

Do we really have to search in that place?

Oh yes, unfortunately we have to find a way somewhere through the limestone core of the pyramid in order to reach the really secret rooms. Suppose we can get into the passage behind the huge stone blocks of the real entrance, then possibly a fairly wide staircase could lead us to a wall at the end of that corridor. We know that behind this wall are the construction rooms above the King’s Chamber. However, it’s not wise to continue this way, it’s impossible to overcome these granite beams above the King’s Chamber. Maybe it’s possible to drill a hole in the western limestone wall in between two layers of granite beams. If lucky we may be able to look inside this supposed corridor [C].
