Cairo Islamic & Christian Giza Sakkara Memphis Dahshur Sakkara Imhotep, an   Egyptian  architect   who  lived  4500  years  ago, is the  one  who  built  this  fabulous  step   pyramid.  He  began  the pyramid as a single story,  then  added  five more levels. He then covered   it   with   fine   limestone.  In  front  of  the  pyramid,  he built  a  stone  structure   which   contains   a  wooden   box    with two  peep-holes.  Looking  through  it,  one  may  view a   life-size painted statue of king Djoser . The reason  behind this is to allow the  king's 'Ka' ( or life spirit )  to  communicate  with  the outside world.
