The basic architectural style stayed the same (pediment, entablature, columns, and 3-tiered platform), but the Romans added more stairs that only went up to the front of the building, whereas Greek temples had stairs around every side. Half columns were a new feature, also; these were attached to the solid walls to create a decorative pattern. Basilicas featured a nave (long, wide, central aisle) and an apse (semicircular area at the end of the nave). (More on this when we get to the Medieval era…)
Examples of Ancient Roman architecture are: baths, amphitheaters, theaters, triumphal arches and bridges, the Colosseum, and the Pantheon—among many others. Another huge innovation at this time was the Roman aqueduct, which was a system that carried water from mountain streams into cities by using gravitational flow.
