The pyramids are doubtless the most easliy recognizable architecture of ancient Egypt. The massive structures jut hundreds of feet into the air, bearing witness to the technological sophistication of their creators.  The first pyramids were, as far as we know, created by  Imhotep the grand Vizier of the king.  Flakes of paint found by archaeologists indicate that the pyramids were painted in brilliant colors at one time.

Pyramids were most often used as elaborate tombs for royalty.  Egyptian religion taught that the soul would wander lost throughout eternity without a physical marker to guide it.  The importance of the physical to guide the soul resulted in the process of mummification, and in the construction of the mighty pyramids.
