The arch had a height of about 13 meters. It is a quadriform arch that rises on four pillars that form four semicircular arches. Each pillar sits on a base topped by a cornice. On the sides facing the Roman road there are pedestals on which probably representative statues or effigies of the time were placed. It is the only arch of this type that is preserved in Spain.
A very striking landmark is the Tetrapylon - an almost square building of about 10 m height with a characteristic groined vault, which is supported by pylons.
