At the big, spacious Square of Petar Zoranić, there are ruins surrounded by fence and the tall, large column nearby. It will be hard to miss your guide dressed as a Roman soldier, especially with red tunic quite visible despite the armour.
The tour finishes at the ruins of the Roman Forum right in the centar of the ancient city. It offers further possibility to explore heritage of Zadar by visiting Arheological museum of Zadar located by Forum and having beautiful collection from Roman period on the 1st floor.
