Ancient Roman Architecture

Rome took the Greek orders and added the arch, vault, dome, and concrete — engineering classical beauty into vast public space at imperial scale.

  • The round arch, barrel/groin vault, and dome
  • Roman concrete enabling vast spans and interiors
  • Classical orders used as applied decoration on arcades
  • Monumental public buildings: baths, basilicas, amphitheaters
  • Engineering at scale: aqueducts, bridges, road infrastructure
