These include several important carved Late Roman sarcophagi, reliquaries from various periods, and Baroque paintings, with three by Louis Finson.

The west portal is one of the treasures of Romanesque sculpture, presenting the story of the Apocalypse according to St. John, and the Gospel of St. Matthew.

Christ is seated in majesty in the tympanum, with the symbols of the Evangelists around him; according to the most common interpretation, they are the man of St. Matthew, the lion of St. Mark, the ox of St. Luke, and the eagle of St. John.

On the lower level, separated by pilasters and columns of dark stone, are statues of saints connected with the history of Arles; on the left, St. Bartholomew, St. James the Great, St. Trophimus, St. John the Evangelist, and St. Peter; and on the right, St. Philip, St. James the Just, St. Stephen, St. Andrew, and St. Paul.

Under a reform instituted by Pope Gregory, the Canons were required to live like monks, with a common dormitory, refectory and cloister within the cathedral enclosure, separated by a wall from the city.

The capitals of the columns depict Lazarus coming out of his tomb between Martha and Mary; Abraham about to sacrifice his son; and Balaam on his ass being stopped by a sword-wielding angel.

The Resurrection story concludes on the northeast corner pillar with the Ascension of Jesus, next to the figures of Saint Paul and St. Andrew on either side of St. Stephen.

The capitals in the third bay illustrate the entry of Christ into Jerusalem, Palm Sunday and Pentecost, and a knight striking down an adversary, and then walking over to a lady; possibly representing Constantine defeating paganism and then being thanked by the mother church.

The Southern Gallery probably dates to the 1380s or 1390s, and is built in the Gothic style, with pointed arches intersecting vaults resting on colonnettes with foliated capitals.

The capitals in the southern gallery are entirely devoted to the story of St. Trophimus; the first shows St. Trophime blessing the Alyscamps burial ground, and dedicating an oratory to the still-living Virgin Mary; the next four show a miracle performed by the intervention of St. Trophime; he brings back to life a knight and nine of his relatives unjustly sentenced to death by the Emperor Charlemagne for slapping the archbishop Turpin.

The Western Gallery probably dates to about 1375, and is devoted to religious figures and scenes popular in Provence; from south to north: the stoning of St. Stephen; Samson slaying the lion and yielding to Delilah; Saint Martha and the Tarasque; Mary Magdalene kissing Christ's feet; the Annunciation in a Gothic setting; the Coronation of the Virgin; and the Pentecost.
