Yes, the Great Sphinx of Giza has been the subject of intense exploration and scientific study for centuries, though much of its "inner" secrets remain a blend of archaeology and myth. Historically, researchers like Mark Lehner and Zahi Hawass have mapped known passages, such as one in the Sphinx’s "rump" likely dug by ancient treasure hunters. In 2026, advanced non-invasive technologies like muon tomography and ground-penetrating radar (GPR) are frequently used to scan the bedrock beneath the monument. While sensationalist headlines often claim "hidden libraries" or "hall of records" have been found, legitimate archaeologists have only confirmed natural fissures and man-made shafts used for restoration or ancient drainage. Exploration is strictly controlled by the Egyptian Ministry of Tourism and Antiquities to prevent structural damage to the fragile limestone. While we have physically entered every known cavity, the quest for undiscovered chambers continues to drive modern expeditions, using 21st-century sensors to peer through the stone without ever picking up a chisel or a drill.
