Argos is a city and a former municipality in Argolis, Peloponnese, Greece. A settlement of great antiquity, Argos has been continuously inhabited as at least a substantial village for the past 7,000 years. In classical times Argos was a powerful rival of Sparta for dominance over the Peloponnese, but was eventually shunned by other Greek city-states, after remaining neutral during the Greco-Persian Wars. Numerous ancient monuments can be found in the city today, the most famous of which is the Heraion of Argos, though agriculture (particularly citrus production) is the mainstay of the local economy.
The city of Argos was believed to be the birthplace of the mythological character Perseus, the son of the god Zeus and Danaë, who was the daughter of the king of Argos, Acrisius.
