An intriguing discovery has been made by researchers on the Giza plateau in Egypt: an underground “anomaly” that appears to be L-shaped. This structure, located near the 4,500-year-old pyramid of Cheops or Khufu, is believed to have been part of a royal cemetery from the time of the pharaohs.

The Japanese-Egyptian research team used radar and layer imaging to scan the ancient cemetery, revealing the unusual shape at a depth of about two meters underground. The L-shaped structure is 10–15 meters long and was filled with sand after construction, indicating it may have once been an entrance to a deeper space.

Although no excavations were conducted, the researchers believe this discovery could be a significant underground archaeological structure related to the mastaba tomb buildings found in the area. Mastabas are typically rectangular buildings, but L-shaped ones are known to exist. The origin of this particular structure remains a mystery, but researchers are eager to investigate further.

Harvard University professor of Egyptology Peter Der Manuelian emphasized the importance of this find, noting that the untouched nature of the discovery area adds to its intrigue. While similar L-shaped chapels have been found above ground at Giza, this underground anomaly presents a unique and unexplored opportunity for archaeological research.
