The roman republic
which characteristic of roman culture are most reflected in its architecture

Life in the Roman Republic revolved around the city of Rome, and its famed seven hills. The city also had several theaters. gymnasiums, and many taverns, baths and brothels. Throughout the territory under Rome's control, residential architecture ranged from very modest houses to country villas, and in the capital city of Rome, to the residences on the elegant Palatine Hill, from which the word "palace" is derived. The vast majority of the population lived in the city center, packed into apartment blocks.
