Hidden Air Filled Chambers in Menkaure Pyramid Indicate a New Entrance

Researchers from Cairo University and the Technical University of Munich (TUM), working under the ScanPyramids Project, have discovered two air-filled anomalies behind the eastern façade of the Menkaure Pyramid, the smallest of Giza’s three great pyramids.
Using advanced non-destructive techniques — including georadar, ultrasound, and electrical resistivity tomography (ERT) — the team confirmed the existence of two voids beneath the granite blocks. The anomalies are located about 1.4 m and 1.13 m behind the pyramid’s polished eastern surface and measure roughly 1 × 1.5 m and 0.9 × 0.7 m.
This discovery supports a long-standing hypothesis that the pyramid may have a second, hidden entrance on its eastern side. The smooth stonework in this area, similar to that around the known northern entrance, first led researchers such as Stijn van den Hoven to propose the idea in 2019.
The research team credits the success to an “Image Fusion” analysis, which combined multiple datasets to produce highly accurate imaging of the pyramid’s interior.
Professor Christian Grosse of TUM stated:
“After confirming a hidden corridor in the Great Pyramid in 2023, this new discovery in Menkaure marks another major step. Our results make the hypothesis of an additional entrance very plausible.”
