The ancient structure built as a tomb for an Egyptian pharaoh is the Great Pyramid of Giza. Located on the Giza Plateau, it is one of the Seven Wonders of the Ancient World and the largest of the three pyramids in the Giza pyramid complex. Commissioned for Pharaoh Khufu (also known as Cheops), the Great Pyramid was constructed around 2580–2560 BCE and exemplifies the architectural and engineering prowess of ancient Egypt. Its precise alignment with the cardinal points and the use of massive limestone blocks showcase the skills of the builders and their understanding of mathematics and astronomy.
