The Great Pyramid of Giza (Pyramid of Khufu)

The Great Pyramid of Giza (also called the Pyramid of Khufu or Cheops) was constructed in the Fourth Dynasty of Egypt's Old Kingdom as a royal tomb for Pharaoh Khufu. Scholarly sources date its construction to roughly the 26th century BCE (commonly cited ranges include c. 2589–2566 BCE or c. 2600 BCE) and report a construction period of about 20–30 years. Over millennia the pyramid has been visited by explorers and looters, has remained the best-preserved of the ancient Seven Wonders, and continues to be a focus of archaeological research. Modern scientific investigations have applied non‑invasive imaging techniques (including cosmic-ray muon scans) and reported the presence of previously unknown internal voids or corridors within the pyramid. These discoveries are discussed in archaeological and popular-science sources as physical, structural anomalies to be investigated rather than as evidence of supernatural phenomena. The site has also generated long-standing legends and speculative interpretations (often grouped under "pyramidology"), including symbolic claims such as proposals that the pyramid encodes funerary texts like the Book of the Dead. The supplied research notes do not document verified contemporary paranormal encounters, named spirits, or haunting phenomena tied to the site. Culturally, the Great Pyramid functions as a global symbol of ancient Egyptian monumental architecture and funerary practice; its age, tomb function, and internal mysteries have made it a focal point for both mainstream archaeological inquiry and speculative or esoteric traditions.
