Ancient Roman Architecture
Also known as Roman architecture, Classical Roman
Rome took the Greek orders and added the arch, vault, dome, and concrete — engineering classical beauty into vast public space at imperial scale.

About the style
Ancient Roman architecture married Greek decorative language to Roman engineering, and in doing so invented much of the built world that followed. The Romans adopted the classical orders but treated them as ornament applied to a new structural toolkit: the round arch, the barrel and groin vault, the dome, and — decisively — concrete (opus caementicium), which let them span and enclose space on an unprecedented scale. They built for the public and the state: basilicas, baths, aqueducts, triumphal arches, amphitheaters, and the great coffered dome of the Pantheon. Where Greek architecture is about the perfected object, Roman architecture is about enclosed space and the organization of empire.

A Greek-style triangular pediment crowns the porch — classical ornament fronting a radically un-Greek domed concrete rotunda behind.
Monolithic granite columns with carved Corinthian capitals form the deep entrance porch — the Greek order used as a grand applied frontispiece.
Behind the porch, the cylindrical concrete drum carries the famous dome — the Roman contribution that the portico's classicism conceals.
The axial entrance sits under the portico — a single processional approach into a vast circular interior lit only by the oculus.
