This was in the area of the port, outside the city walls. The builders took advantage of a marked slope leading down to a flat area to construct what must have been imposing tiers of seating. In spite of the appalling treatment they have suffered over the centuries, the ruins still retain, if only partially, the three essential structural elements of a Roman theatre: the cavea (tiers of seating), the orchestra and the scaena. The former opulence of the theatre can be seen in the monumental capitals and the statues with imperial inscriptions of men in togas and armour, which would have formed part of the scaenae frons. These can now be seen in the National Archaeological Museum of Tarragona.
