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 storey, then added five more levels. He then covered it with fine limestone. Infront 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 Zoser . The reason behind this is to allow the king's 'Ka' (or life spirit) to communicate with the outside world.
