The significant structure built in Egypt as a tomb for Pharaoh Khufu is the Great Pyramid of Giza. Constructed around 2580–2560 BCE, it is the largest of the three pyramids on the Giza plateau and was originally built as part of a complex that included mortuary temples and smaller pyramids for queens. The Great Pyramid is a testament to ancient Egyptian engineering and architectural skills, consisting of approximately 2.3 million blocks of stone. It served as a monumental burial site intended to ensure the Pharaoh's safe passage to the afterlife, highlighting the cultural importance of death and the afterlife in ancient Egyptian society.
