They often feature elements like columns, pediments, and domes, showcasing symmetry and proportion. Common materials used include marble and limestone, which add to their grandeur. These buildings often serve important cultural and civic functions, such as temples, government buildings, and theaters. Notable examples include the Parthenon in Athens and the Pantheon in Rome. Classical architecture has influenced many styles throughout history, including Renaissance and Neoclassical designs, which continue to be admired today.
