The ancient civilization known for the pyramids is ancient Egypt. This civilization arose around the Nile River and flourished for millennia, creating monumental architecture, art, and a complex system of writing known as hieroglyphics. The pyramids, built as tombs for pharaohs, exemplify the Egyptians' engineering prowess and religious beliefs. The most famous pyramids are the Great Pyramids of Giza, including the Pyramid of Khufu, which is one of the Seven Wonders of the Ancient World. These structures reflect the civilization's advanced understanding of mathematics and labor organization, as well as their deep spiritual connection to the afterlife.
