Twenty-two centuries in the history of Parma are reflected in this major excavation report. Between 1988 and 1992, during a re-building phase, archaeological research was carried out in the foundation levels of the Cassa di Risparmio di Parma e Piacenza (C.di R.) Bank in Parma, Emilia-Romagna. The building faces the southern area of Piazza Garibaldi (partly corresponding to the forum of the Roman city), and is set against the south side of St. Peter's church, which is founded on the most important temple of the colony and borders two roads of the colonial urban system - via dell'Universita and via Giordano Cavestro. This work presents the archaeological findings."
