Athens is the ancient Greek city associated with the Parthenon and a major setting in Assassin's Creed Odyssey.
Odyssey takes place during the Peloponnesian War in the fifth century BCE. Players can visit Athens, explore its districts, and encounter historical figures including Pericles and Socrates. The Acropolis and Parthenon help establish Athens as a political, cultural, and architectural center.
Sparta is equally important to the game's story and is the protagonist's ancestral homeland, but it is not the city associated with the Parthenon. Corinth and Thebes are also real Greek cities represented in the game world, though neither is the answer to this landmark-based question.
