The structure known for having been built by the ancient Egyptians is the Great Pyramid of Giza. This iconic landmark was constructed around 2580–2560 BC for the Pharaoh Khufu and is considered one of the Seven Wonders of the Ancient World. Originally standing at 146.6 meters, it was the tallest man-made structure for over 3,800 years. The pyramid was built using millions of limestone and granite blocks, and its design reflects the Egyptians' advanced understanding of architecture and engineering. It served as a tomb, reflecting the civilization’s beliefs about the afterlife and the significance of the pharaoh's role.
