The work of the Director Plan for the Cathedral of Tarragona has allowed us to make a revision regarding the knowledge, chronology and features of the sacred area of the Concilium Provinciae Hispaniae Citerioris. We present diverse elements of architectural and sculptured decoration recovered from constructive levels of 1st century A.D, and the 6th century A.D levels of re-use and transformation, in contemporary constructions. All these elements ratify the process of imitation of the Forum Augustum made in the capital of the Hispania Citerior.
