Dashur: Black Pyramid of Amenemhat III. The Black Pyramid of Dashur was the first pyramid built by Amenemhat III (of the Middle Kingdom of Ancient Egypt) during the early part of his reign.

The Great Pyramid of Giza was built for the Fourth Dynasty Pharaoh Khufu (or Cheops), and was completed around 2560 BCE. It is part of a complex of 3 large pyramids in the Giza Necropolis located in modern Cairo, Egypt. The Great Pyramid is the largest of the three pyramids, and it is part of its own smaller complex that also contain 3 small pyramids that were built for Khufu's wives. It took approximately 20 years to complete, and several theories are debated by scholars as to how it was built and by whom.
