Agora
An agora (αγορά), meaning "marketplace" in English, was a place in an ancient Greek polis or city-state that plays the role as the market and a forum for citizens. The agora was already a part of a city by the time of Homer (probably the 8th century BC). The agorae developed with the establishment of city-states after the Mycenaean civilization fell.
The most famous agora was the one in Athens. The Agora Open Air Museum of Izmir is one of the best preserved agorae in the world.
The word agoraphobia, derives from agora, denotes the fear of critical public situations, such as the marketplace.
Agora also means a place of assembly in any Ancient Greek state. It is sometimes used in modern language to refer to a crossroads, either metaphorically (the point or concept which links, or is the crossroads of multiple related concepts), or literally, a point at which many physical roads or paths meet.
