Greek Classical architecture is comprised of three orders: Doric, Ionic, and Corinthian.
The first of these Greek styles, the Doric, has roots in three ancient locales: Egypt, Mycenae, and Greece. The plan or layout of the Greek Doric temples has its most distinct source in the Mycenaean construction, similar to that of the Mycenaean megaron. However, the upwards taper of the columns in Greek temples indicates a close relationship to the columns or half-columns of ancient Egyptian buildings. One major difference, however, between the Egyptian and Greek structures rests with the presentation of the buildings: while Egyptian edifices were meant to be experienced from inside, the Greek buildings had just the opposite purpose, with congregations meeting on the outside. Nonetheless, the stone-cutting and the geometry of the Egyptians had a major influence on the building methods of the Greeks.
