The ancient structure built as a tomb for Pharaoh Khufu is the Great Pyramid of Giza. Constructed around 2580–2560 BC, it is one of the Seven Wonders of the Ancient World and remains a testament to ancient Egyptian engineering and architecture. The pyramid served not only as a burial site but also as a symbol of Khufu's power and religious significance, reflecting the society's beliefs in the afterlife. It was originally encased in smooth white limestone, giving it an impressive and majestic appearance.
