Overview
- Researchers report two air-filled cavities behind the eastern facade of the Menkaure pyramid at depths of about 1.4 m and 1.13 m.
- The voids measure roughly 1.0 × 1.5 meters and 0.9 × 0.7 meters, according to data published in NDT & E International.
- The team combined electrical resistivity tomography, ground‑penetrating radar and ultrasound in a multi‑year, non‑invasive survey.
- A distinctly polished granite patch on the east face—visually akin to finishing around the known north entrance—supports the entrance hypothesis.
- ScanPyramids (Cairo University and TUM) plans further tests, with outside experts urging caution as a 2019 proposal by Stijn van den Hoven gains empirical support.
