How is the Acropolis of Athens different from the Parthenon?

The Acropolis of Athens is a natural citadel and sanctuary, a high, walled hill containing chief religious and municipal buildings. The Parthenon, on the other hand, is the most famous temple located on the Acropolis, constructed as a shrine to Athena and a treasury. While the Acropolis is the entire ancient district, the Parthenon is a specific structure within it, built during the 5th century BCE and considered a culmination of Doric order architecture. The Acropolis served as a defensive and religious center, while the Parthenon was its primary religious and financial hub.123
