Pyramids of Giza, three 4th- dynasty (c. 2575–c. 2465 bce) pyramids erected on a rocky plateau on the west bank of the Nile River near Al-Jīzah (Giza) in northern Egypt. In ancient times they were included among the Seven Wonders of the World.
The pyramid's smooth, angled sides symbolized the rays of the sun and were designed to help the king's soul ascend to heaven and join the gods, particularly the sun god Ra.
A pyramid is a structure or monument, usually with a quadrilateral base, which rises to a triangular point.
