Argos is on the northern tip of the Gulf of Argulis. The first settlement at Argos is estimated to be 3000 BCE. Due its location on the gulf Argos profited by trade with its abundance of crops. According to some, Argos was known for music and poetry. Argos was a powerful city-state on the Peloponnese peninsula, until Sparta defeated the city in 550 BCE and again in 494 BCE.
When we visited, there was not a lot of the site reconstructed. The pictures below give a sense of the foundations of the buildings. After our visit I checked a number of websites. At the Britannica website, there were was picture of a large Roman theater at Argos. A search with google earth revealed the ancient theater to be in the heart of the urban Argos area. We were high above the modern city. We missed the Roman theater, which from pictures on the web looked extremely impressive. I copied an image off the web and put it at the end of post.
