A view of a portion of the interior of the so-called "Septimius Severus warehouse." In fact, this storage area was constructed earlier, possibly during the reign of Marcus Aurelius (r. A.D. 160–180) of the "Antonioni Dynasty."
Note the rib vaulting.
The warehouse was situated on the western edge of the octagonal Trajan Harbor. Portions of the walls of the second floor are still preserved.
