The culture known for its ancient pyramids is that of Ancient Egypt. These monumental structures, primarily built as royal tombs, symbolize the grandeur and architectural ingenuity of the civilization that flourished along the Nile River. The most famous pyramids, located at Giza, include the Great Pyramid of Khufu, one of the Seven Wonders of the Ancient World. Constructed between 2580 and 2560 BC, these pyramids showcase the Egyptians' advanced engineering, mathematics, and labor organization. Beyond their burial function, the pyramids reflect the Egyptians' beliefs in the afterlife and their desire to ensure a prosperous existence beyond death.
