In the middle of the 3000 B.C., about 2631 B.C. to 2498 B.C. In Giza, the Nile Delta, three great pyramids were built by three emperors of the fourth dynasty, Kufu, Havra and Menkaura, in 2600 BC, 2500 BC. It is the most mature representative of the ancient Egyptian pyramids, which we often call the Great Pyramid. In the suburbs of Cairo today, it is mainly composed of the Great Pyramid, Havra, Menkaura Pyramid and the Great Sphinx. There are also many "Mastaba" and small pyramids around. The pyramid, the Sphinx, is the representative of Egypt in many people's minds, and finally has the opportunity to see the legend in their minds and witness a long history. In the open desert, the pyramids that have stood for thousands of years are shocking and awe-inspiring. They deserve to be the crystallization of ancient Egyptian civilization.
