Which of the following is a defining trait of Greek architecture?

• A. Post-and-lintel construction with columns surrounding structures
• B. Arches and vaults
• C. Flying buttresses
• D. Concrete construction

Answer: (A)

Greek architecture is defined by post-and-lintel construction, where vertical columns support horizontal beams across the top to form a stable frame. This approach creates temple exteriors with a rhythm of columns and carefully proportioned spaces, expressed in the three classical orders—Doric, Ionic, and Corinthian. Arches and vaults are Roman innovations that enable curved interiors, while flying buttresses belong to Gothic architecture and serve different structural needs. Concrete construction comes later in broader ancient and medieval building traditions rather than being a hallmark of early Greek practice. So the key defining trait is the use of columns supporting horizontal lintels in a post-and-lintel system.
