The center of political and commercial interaction in the Ancient Greek polis was the agora. The word essentially means a gathering place or an open space, and in all Greek city states, the agora was central to all aspects of daily life and commerce. As the agora developed as a civic space, particularly from the sixth century BCE onward in Athens, the architectural splendor of the buildings associated with it became an ever more obvious demonstration of the power and glory of Athenian democracy. In its earliest forms, an agora in maritime cities was invariably situated near the sea, while in inland urban centers, it was usually located at the foot of the hill that normally provided the city’s ultimate defense. 

The agora was always the oldest part of any city. Being the commercial hub of the area, it also became the center of the religious and political life of the polis. In Homer’s time, an agora might have seats for the comfort of the citizens that had assembled to consult with one another. The city’s oldest sanctuaries were always located either in or very close to the agora itself, and the first festive games were held in its open space.

The Roman Empire is the most famous in history, and the center of the far-reaching empire’s activities was located in the Forum, a low area between the Capitoline and Palatine hills in Rome. The topography held a great deal of significance for Romans, and consequently, so many layers of myth were laid on top of the landscape and buildings that it is difficult to separate legend from actual historical fact. As a low-lying area near the Tiber river, the Forum was subject to much flooding, and even into the 20th century, the Forum area could flood upwards of over 40 feet above sea level. This would factor significantly in the imagination of Romans, who later ascribed the flooding with saving the city’s founders, Romulus and Remus, from execution.
