By Ictinus and Callicrates
From the northwest
Dedicated to the virgin Athena Parthenos, the great Parthenon was designed by the architects Ictinus and Callicrates and built over the years 447-432 B.C. Basically it is a simple rectangular building, 237 feet long by 110 1/2 feet wide, with Doric columns around its four sides, supporting an architrave, frieze, and cornice. A pediment on each end rises to a slanting roof. With the exception of the roof frame and parts of the ceiling, the entire temple is constructed in marble. To this day the Parthenon remains the masterpiece of consummate proportions.
