How Did Greek Architecture Influence Roman Architecture

Although the Romans were significantly influenced by the Greeks, they did in fact make many of their own architectural discoveries that allowed them to build massive buildings, extensive roadways, and amazing aqueducts. Indeed, the Romans are the masters of modern architecture, with their inventions of both concrete and the arch ultimately changing the face of the world.
The True Arch: While the Greeks use arches, they did not use it for their structures, except for drainage systems and tunnels. The Romans, however, learned about the corbeled arch from the Etruscans, which was formed by stones laid on top of each other with each level of stones moving slightly inward. Although useful, the corbeled arch was unable to build the imposing structures
Contrary to common belief, Romans did not invent the original mix of concrete, as it has been found to have existed in ancient Greece in an ineffective form. The Romans, however, perfected their own recipe, which was made with lime combined with water, and a fine volcanic ash, called pozzolana. Additionally, the Romans would mix their concrete with small stones to add strength, and called this combination opus caementicium (Muscato, n.d.). Using concrete, the Romans quite literally paved their way across the known world, building concrete roads across over 55,000 miles of Europe, Africa, and Asia. "Roadways were the lifeblood of Ancient Rome" (Andrews, 2014). Indeed, as mentioned earlier, their flat, straight roads allowed Romans to move goods, soldiers, and information swiftly across the Empire. It is likely that without their astonishing roadways, Rome could not have maintained its grip on so much territory for so long.
