Two other pyramids were built at Giza for Khufu’s successors Khafra (2558-2532 B.C) and Menkaura (2532-2503 B.C.).
The Old Kingdom began with the third dynasty of pharaohs. Around 2630 B.C., the third dynasty’s King Djoser asked Imhotep, an architect, priest and healer, to design a funerary monument for him; the result was the world’s first major stone building, the Step-Pyramid at Saqqara, near Memphis. Egyptian pyramid-building reached its zenith with the construction of the Great Pyramid at Giza, on the outskirts of Cairo. Built for Khufu (or Cheops, in Greek), who ruled from 2589 to 2566 B.C., the pyramid was later named by classical historians as one of the Seven Wonders of the Ancient World. The ancient Greek historian Herodotus estimated that it took 100,000 men 20 years to build it. Two other pyramids were built at Giza for Khufu’s successors Khafra (2558-2532 B.C) and Menkaura (2532-2503 B.C.).
