Cheops pyramid: new chamber in world wonder confirmed

NEWS RELEASE
TUM researchers confirm assumed chamber
Important find in the Cheops pyramid of Gizeh
- New chamber discovered in largest of the Egyptian pyramids
- Munich researchers verify long-held assumption
- Function and purpose of the chamber now to be investigated
An international research team has discovered a previously unknown chamber in the Cheops pyramid of Gizeh. As early as 2016 measurements had given reason to assume the existence of a hidden hollow space in the vicinity of the chevron blocks over the entrance. Now scientists from the Technical University of Munich (TUM) have used ultrasound and endoscopy to make an important contribution to confirming this assumption. The status of the Egyptian pyramid as one of the best investigated structures in the world makes this find particularly important.
The Cheops pyramid is considered the largest and oldest of the pyramids of Gizeh. As part of one of the Seven Wonders of the Ancient World it has been thoroughly explored; however, the structure still holds many undiscovered secrets. TUM researchers have now solved one more of the pyramid's mysteries. As part of the international research team "ScanPyramids" the Munich scientists have proven the existence of an empty chamber which was until now only posited based on measurement data. The hollow space is located above the original entrance to the pyramid, which is not accessible to the public.
Assumption confirmed
In 2016 several measurements by Japanese and French researchers provided evidence for the existence of the chamber. The TUM research group has been on board since 2019, helping to explore the pyramid for hidden structures. They use various non-destructive testing methods which make it possible to look into the stone blocks and the areas behind them. "The pyramids are a World Heritage Site. This means we have to be especially careful when conducting our investigations so that we don't damage anything. We're working on the Cheops pyramid with radar and ultrasound measuring devices that can be used on a non-destructive basis, and in part even contact-free," says Prof. Christian Grosse, TUM Chair of Non-Destructive Testing.
Chamber is larger than expected
The initial measuring devices provided a good first impression of the situation. The scientists then used endoscopy to confirm the assumption. The team found an opening between the stones of the chevron, a solid stone construction, through which they were able to run a tube into the chamber. They then used this tube as a guide for an endoscopic camera lens. The camera confirmed the existence of the hollow space. "Discovering a hollow space in a pyramid is already something special. But the fact that this chamber is large enough to accommodate several people, well, that makes the discovery even more important," says Prof. Grosse.
The chamber is larger than researchers had assumed in the past. The original measured data pointed to the existence of a corridor at least five meters long; however, according to initial estimates, the length of the chamber considerably exceeds this length. There are no footprints or other evidence of human activity to be seen within the chamber. Thus the research group assumes that this room has not been seen by anyone for approximately the last 4,500 years.
New chamber calls for further research
Determining the former purpose of the newly discovered chamber and what is located behind the back wall of the room will require additional research. The confirmed findings highlight the need for further investigation of Egyptian pyramids and in particular the value of the new approach using a combination of various testing technologies and procedures.

Work at the pyramid was conducted in collaboration with and under the supervision of the Egyptian Supreme Council of Antiquities and the Egyptian Ministry of Tourism and Antiquities. "ScanPyramids" is coordinated by Cairo University (Egypt) and the HIP.Institute (France). In addition to TUM, the following organizations are also involved: Nagoya University (Japan), KEK (High Energy Accelerator Research Organization - Japan), CEA (French Alternative Energies and Atomic Energy Commission - France ), Laval University (Canada), INRIA (French Institute for Research in Computer Science and Automation - France), CNRS (French National Centre for Scientific Research - France). Additional partners and financial supporters were: Dassault Systèmes, Whatever The Reality, Emissive, La Fondation Dassault Systèmes, NHK, Suez, Le Groupe Dassault, Batscop, Itekube, Parrot, ILP, Kurtzdev, Gen-G, Schneider Electric, Octave & Octave. TUM was directly supported by TUM IGSSE and the DAAD (German Academic Exchange Service).

The Technical University of Munich (TUM) is one of Europe’s leading research universities, with more than 600 professors, 50,000 students, and 11,000 academic and non-academic staff. Its focus areas are the engineering sciences, natural sciences, life sciences and medicine, combined with economic and social sciences. TUM acts as an entrepreneurial university that promotes talents and creates value for society. In that it profits from having strong partners in science and industry. It is represented worldwide with the TUM Asia campus in Singapore as well as offices in Beijing, Brussels, Mumbai, San Francisco, and São Paulo. Nobel Prize winners and inventors such as Rudolf Diesel, Carl von Linde, and Rudolf Mößbauer have done research at TUM. In 2006, 2012, and 2019 it won recognition as a German "Excellence University." In international rankings, TUM regularly places among the best universities in Germany.
