Most ancient than all the Fori is the Roman one: it was constructed on a swampy area used like sepulchrete and cleared around to the 600 b.C.

The area was paved in battered earth and was shared in two parts: the comitium, destined to the political activity, and the one destined to the civic market. The Forum was infact the center of the political (senate and people), religious and economic life of the city.

During the imperial age, a column in honor of the emperor Foca was erected, last Roman monument, but the grown requirements of propaganda from the powership, made it more than other a representation public square. Therefore in order to acquit to this task gradually other Fori have been created, also said "imperial" (Cesar's, Augusto's, Nerva's, Traiano's).
