The Old Kingdom is perhaps best known, however, for the large number of pyramids, which were constructed at this time as pharaonic burial places. For this reason, this epoch is frequently referred to as "the Age of the Pyramids." The first notable pharaoh of the Old Kingdom was Djoser of the Third Dynasty, who ordered the construction of the first pyramid, the Pyramid of Djoser, in Memphis' necropolis of Saqqara.
