The primary architectural feature of the Parthenon is its use of the Doric order, which is characterized by simple and sturdy columns with fluted shafts and no base. This ancient temple, dedicated to the goddess Athena, exemplifies classical Greek architecture through its harmonious proportions and exquisite detailing. The Parthenon also incorporates optical illusions, such as slight curvature in the columns and steps, designed to create a visually perfect structure. Its sculptures and friezes, depicting various mythological themes and historical events, enhance its artistic value, making the Parthenon a symbol of ancient Greek democracy and cultural achievement.
