古王國時期
The Buried Pyramid (also called the Pyramid of Sekhemkhet) is an unfinished step pyramid constructed c. 2645 BC for Sekhemkhet Djoserty. This pharaoh was the second of the Third Dynasty of Ancient Egypt, which reigned over Egypt circa 2686–2613 BC and is usually placed at the beginning of the Old Kingdom of Egypt. Many historians believe that the third dynasty played an important role in the transition from Early Dynastic Period of Egypt to the Age of the Pyramids.
