What structure was at the center of public and religious life in Greek city-states?

The agora

The agora, the central gathering place in Greek city-states, served as a focal point for public and religious life, as well as a market. As the hub for political, social, and economic affairs, the agora reflected the democratic organization of Greek society. It demonstrates the importance of citizen participation and public debate in antiquity. The ruins of these spaces, such as those in Athens, still offer a glimpse into the daily life of the ancient Greeks today, highlighting their contribution to the development of political and social concepts that endure.
