The pyramid of Djoser, designed by Imhotep in 2600 BC. This building is noteworthy for a host of reasons. That its architect is known is a historical first, besides it being the first Egyptian pyramid. The columns in the arcades were designed to look like papyrus plants and were a direct inspiration for the much later classical Greek column orders. The pyramid itself was designed as a stack of Mastaba tombs, the traditional Egyptian tomb design.
