The Roman Empire is renowned for its sophisticated legal codes and impressive architecture. Its legal system, which laid the foundation for many modern legal principles, emphasized concepts such as the presumption of innocence and the rights of the accused. The Twelve Tables and later the Corpus Juris Civilis were pivotal documents that organized and codified Roman law. Architecturally, the Romans are noted for innovations including the development of concrete, the arch, and aqueducts, which enabled them to construct monumental structures like the Colosseum and the Pantheon. These contributions have had a lasting impact on Western civilization, influencing law and architectural practices across centuries.
