The Great Pyramid of Giza has guarded its secrets for more than 4,500 years, yet a cavity hidden just behind its northern face has only now come into clear view. Using a 6 millimeter endoscope threaded through a tiny joint in the stonework, researchers have revealed a sealed corridor that had never been seen by modern eyes.
The discovery crowns years of patient scanning and hints that the monument still contains unknown spaces, perhaps even untouched ritual architecture. I see this slim camera not as a gimmick, but as the final, surgical step in a long campaign to read the pyramid’s interior without breaking it open.
The long hunt for a void in the Great Pyramid’s north face
The sealed passageway did not appear out of nowhere. It is the product of the ScanPyramids project, an international effort that has spent years probing Egypt’s largest pyramid with non invasive tools such as muon radiography, infrared thermography, and 3D reconstruction. According to the project’s own description, the team identified a void on the monument’s northern side, using particle detectors and other sensors to map density differences inside the stone mass.
That anomaly, located behind the northern face and above the original entrance, was eventually designated the Named “ScanPyramids North-Face Corridor” (SP-NFC), a label that reflects both its position and its elongated shape. The same technical description notes that this void lies between 17 and 23 metres from the outer surface of the Great Pyr, which corresponds to 56 and 75 feet, and that it has a corridor-like profile rather than a simple pocket of air. Those precise figures matter, because they show that the cavity is not a minor crack but a deliberate architectural volume running deep inside the core blocks.
From muons to a 6 mm endoscope
Once the North Face Corridor had been inferred from particle tracks and thermal anomalies, the challenge was to see it without carving a new doorway into the Great Pyramid of Giza. The team turned to a technique that has become a hallmark of modern conservation, inserting a very small camera through an existing joint in the stonework so that the monument’s fabric remained essentially intact. Earlier reports describe how this non invasive approach, applied about 7 meters above the main entrance on the northern face, allowed researchers to confirm that an empty space lay behind the chevron shaped blocks that frame the original access passage.
Video footage from that 6 millimeter endoscope finally revealed the hidden corridor itself, a straight, roughly 9 meter long space with a flat floor and unfinished ceiling stones that sit just behind the massive chevrons. The images, captured after the camera was threaded through a narrow gap between the blocks, showed the interior surfaces of the cavity and confirmed that the void is not filled with rubble or sand. As one detailed account of the work notes, the endoscope’s view made it possible to match the internal geometry to the earlier muon data, tying the visual evidence directly to the technique that first detected the empty space.
What the sealed corridor looks like from the inside
From the endoscope’s perspective, the corridor is surprisingly austere. Reports from CAIRO describe a chamber about 9 meters in length, with roughly cut limestone blocks forming the walls and ceiling and a floor that appears level but unfinished. One summary of the find notes that the cavity sits behind the northern face of the Great Pyramid of Giza and that its discovery was confirmed by an international team that presented their imagery in CAIRO, underscoring how the visual evidence transformed a theoretical void into a documented architectural feature inside the Great Pyramid of Giza.
Another account, filed from CAIRO, EGYPT, emphasizes that the camera’s images confirmed a corridor first detected by muon scans and that the work was carried out in coordination with Egypt’s Supreme Council of Antiquities. That report stresses that the footage came from a small camera inserted into the masonry, echoing the description of a 6 millimeter endoscope and reinforcing the idea that the team relied on minimally invasive tools to explore the void. In that narrative, the sealed passage is not a grand gallery but a narrow, almost claustrophobic space, yet it is significant enough that the project gave it a formal label and highlighted it as a key result of the Camera Glimpses Hidden Corridor campaign.
Why a 9 meter corridor matters for pyramid engineering
At first glance, a 9 meter long sealed corridor might sound like a minor curiosity inside a monument that rises more than 130 meters high. Yet the location and form of this cavity speak directly to how the pyramid’s builders managed weight and stress around the original entrance. One detailed briefing from Egypt notes that the newly revealed space is about 9 meters in length and that it lies behind the northern face, close to the chevron blocks that frame the access passage, suggesting that it could function as a relieving chamber or structural buffer. That same report stresses that Egypt sees the discovery as part of a broader effort to understand how the Great Pyramid was assembled and how its internal spaces relate to one another, and it frames the 9 meter corridor as a feature that could lead to further archaeological discoveries deeper inside the monument inside the Great Pyramid.
From an engineering perspective, the corridor’s alignment behind the chevrons is particularly suggestive. The chevron blocks above the entrance are massive, triangular stones that help divert weight away from the passage below, and the presence of a hollow space behind them could indicate a deliberate strategy to reduce pressure on the doorway. The fact that the void stretches between 17 and 23 metres from the outer surface, corresponding to 56 and 75 feet, and maintains a corridor-like shape rather than tapering into a pocket, supports the idea that it was designed as part of a system of stress relieving structures. In that sense, the 6 millimeter endoscope has not just shown a hidden room, it has given engineers and Egyptologists a new data point in the ongoing effort to decode the pyramid’s internal architecture as mapped by the North Face Corridor NFC measurements.
A teaser for a larger 2026 revelation
The sealed corridor’s appearance on camera has also fed into a larger narrative about what might still lie hidden inside the Great Pyramid of Giza. In Nov, Egyptologist Zahi Hawass described plans for what he called “a great archaeological discovery that will write a new chapter in the history of the pharaohs,” signaling that Egyptian authorities expect to announce a major finding in 2026. In that context, the North Face Corridor and the 6 millimeter endoscope footage look less like an isolated curiosity and more like an early glimpse of a broader campaign to open up previously inaccessible parts of the pyramid’s interior as Hawass has hinted.
A separate report from Nov, also citing Egyptologist Zahi Hawass and focusing on the Great Pyramid of Giza, frames the hidden corridor as the latest sign that significant spaces remain to be explored inside the monument. That account notes that the latest sign of what might lie hidden surfaced when Hawass spoke about the pyramid and suggested that the timing of the current work aligns with preparations for a 2026 announcement. It portrays the sealed corridor, detected by advanced scanning and probed with a tiny camera, as part of a sequence of finds that could culminate in a headline making revelation about the pyramid’s internal layout in time for the 2026 announcement.
Egyptian officials have been explicit that they see technology as the key to unlocking those future discoveries. One detailed account from Nov, citing Egypt and Renowned Egyptologist Zahi Hawass, explains that the country is preparing to announce an archaeological surprise in 2026 that will “rewrite history” and that this revelation will be tied to areas of the pyramid that were previously inaccessible. That same report stresses that Egypt is using modern tools to reach spaces that could not be explored before, a description that fits the use of a 6 millimeter endoscope to peer into the sealed corridor and suggests that similar techniques may soon be applied elsewhere inside the structure as Egypt prepares its 2026 surprise.
