 The pair of bronze statues depicting Augustus Caesar and Julius Caesar are not the original statues but copies from the last, radical restoration of 1934.However, they are object of discussion as they were incorrectly placed in the internal area occupied by the "statio" and not outside the gate, where they would possibly have more relevance.Built in the 1st century during the Augustan Age or the Flavian Age, the "Porta Principalis Dextra" may predate the construction of the city walls and was perhaps built on the location of an earlier Republican Age gate.
