The ancient structure that served as a tomb for the Egyptian Pharaoh Khufu is the Great Pyramid of Giza. Completed around 2580 BC, it is the largest of the three pyramids on the Giza Plateau and one of the Seven Wonders of the Ancient World. The pyramid was built as a monumental burial site intended to ensure Khufu's passage to the afterlife. It exemplifies the remarkable engineering and architectural skills of the ancient Egyptians, as well as their religious beliefs surrounding death and the afterlife. The Great Pyramid remains a significant cultural and historical icon today.
