The Doric order is one of the three classical orders of ancient Greek architecture, characterized by its sturdy columns and simple, unadorned design. It is the oldest of the orders, originating in the 7th century BC, and is known for its strength and functionality, often used in temples and public buildings. Doric columns are typically fluted and stand directly on the stylobate without a base, giving them a robust appearance. This architectural style emphasizes proportion and harmony, reflecting the values of ancient Greek culture. The Parthenon in Athens is a famous example of the Doric order in use.
