|Although this large and impressive arch is similar to those in Rome (See the Arch of Constantine and the Arch of Titus), this arch is not considered a triumphal arch like those. Rather, it is a commemorative arch erected by the veterans of the Roman legion to commemorate the founding of their city. Eventually the monument was dedicated to the Emperor Tiberius. "When it was built it was near the Via Agrippa which went from Arles to Lyon" (Boullé 7). Like the Arch of Constantine, it has three arches--a taller central arch flanked by shorter arches. The arches are framed by fluted engaged columns on tall plinths. There was probably a bronze quadriga on the top as well as statues.|
|The four facades are oriented to the four cardinal points. This south facade is less well preserved that the opposite face (the north).|
