when was the first step pyramid built in egypt
Pyramid of Djoser The Pyramid of Djoser (or Djeser and Zoser), or step pyramid (kbhw-ntrw in Egyptian) is an archeological remain in the Saqqara necropolis, Egypt, northwest of the city of Memphis. It was built during the 27th century BC for the burial of Pharaoh Djoser by his vizier, Imhotep. It is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration.
Great Pyramid of Giza Based on a mark in an interior chamber naming the work gang and a reference to the fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10- to 20-year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Originally, the Great Pyramid was covered by limestone casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.
