At the heart of the Great Pyramid lies the King’s Chamber, constructed from massive red granite blocks transported over 500 miles from Aswan. Here stands Khufu’s empty sarcophagus—its missing lid fueling debates about whether it was looted or symbolic. Visitors often remark on the chamber’s acoustics; even a whisper can reverberate like a chant, creating an otherworldly atmosphere that adds to its aura of mystery.
