The Giza Pyramids, built to endure an eternity, have done just that. The monumental tombs are relics of Egypt's Old Kingdom era and were constructed some 4,500 years ago. Egypt's pharaohs expected to become gods in the afterlife.
All three of Giza's famed pyramids and their elaborate burial complexes were built during a frenetic period of construction, from roughly 2550 to 2490 B.C. The pyramids were built by Pharaohs Khufu (tallest), Khafre (background), and Menkaure (front).Photograph by James Stanfield.hufu's son, Pharaoh Khafre, built the second pyramid at Giza, circa 2520 B.C. His necropolis also included the Sphinx, a mysterious limestone monument with the body of a lion and a pharaoh's head. The Sphinx may stand sentinel for the pharaoh's entire tomb complex.
