What is one difference between buildings from earlier civilizations ad those from Roman civilization?

One key difference between buildings from earlier civilizations and those from Roman civilization is the use of concrete in Roman architecture. While earlier civilizations primarily utilized materials like mud brick, stone, and wood, the Romans developed advanced concrete techniques that allowed for the construction of larger and more durable structures, such as the Pantheon and aqueducts. This innovation enabled the Romans to create complex architectural forms, including arches and vaults, which were not prevalent in earlier architectural styles.
