from foxnews.com: Archaeologists working near the ancient settlement of Edfu, in southern Egypt, have uncovered a step pyramid that dates back about 4,600 years, predating the Great Pyramid of Giza by at least a few decades. The step pyramid, which once stood as high as 43 feet, is one of seven so-called "provincial" pyramids built by either the pharaoh Huni (reign ca. 2635-2610 B.C.) or Snefru (reign ca. 2610-2590 B.C.). Over time, the step pyramid's stone blocks were pillaged, and the monument was exposed to weathering, so today, it's only about 16 feet tall.
