Classical architecture refers to a style of buildings originally constructed by the Ancient Greeks and Romans, especially between the fifth century BC in Greece and the third century AD in Rome. The style of classical architecture has been reproduced throughout architectural history whenever architects looked to the ancient past for illumination and inspiration, and in search of what they may have regarded as lost ideals.Classical buildings in ancient Greek and Roman times were typically built from marble or some other attractive, durable stone, but since then, they have also been built in brick, concrete and stone. The architecture was primarily trabeated (post and beam) and evolved from timber origins.
