The Upuaut Project | The Closed Door Inside the Great Pyramid

Last year we experienced the excitement around the discovery of the North Face Corridor, and in 2017 the Big Void in the Great Pyramid made headlines around the world.

Such discoveries can inspire a generation of enthusiasts and that’s precisely what happened to me in the early 1990s.


In March 1993, Rudolf Gantenbrink led a project into the Great Pyramid, guiding a robot through the four pyramid air shafts, and on the robot’s journey into the Queen’s Chamber Southern Shaft a major discovery was made.


Gantenbrink’s work was ground-breaking. Nobody had ever seen into these shafts before. He discovered that the Queen’s Chamber Southern Air Shaft did not extend to the outer edge of the pyramid. His robot came face to face with an unexpected find, a door covering the shaft, with two metal pins protruding out of it.

Thankfully, I have been given permission to publish the original 1995 documentary, titled Robot Journey into the Past, which document’s Gantenbrink’s journey of discovery.


So, in this 1 hour special documentary from 1995, please enjoy this piece of history, as we remember the work on Rudolf Gantenbrink nearly 30 years later.
