Classic architecture refers to the architectural style that draws inspiration from the ancient civilizations of Greece and Rome. Characterized by its use of columns, symmetry, and proportion, this style emphasizes harmony and balance. Notable elements include Doric, Ionic, and Corinthian columns, as well as pediments and domes. This architectural style has influenced many later movements, including the Renaissance and Neoclassicism. Classic architecture is often seen in significant buildings such as the Parthenon in Athens and the Pantheon in Rome, showcasing the enduring legacy of these ancient designs in modern structures.
