The Pyramid of Khufu, also known as the Great Pyramid of Giza, is the largest of the three pyramids located on the Giza Plateau in Egypt. Built around 2580–2560 BCE during the reign of Pharaoh Khufu, it originally stood at 146.6 meters (481 feet) tall. The pyramid was constructed using approximately 2.3 million blocks of stone, showcasing the advanced engineering skills of the ancient Egyptians. The Great Pyramid served as a tomb for Khufu and is part of a complex that includes smaller pyramids, temples, and the Sphinx. It is the only surviving structure of the original Seven Wonders of the Ancient World, reflecting the grandeur and significance of ancient Egyptian civilization.
