This store building has been dated to the Trajanic period (opus reticulatum with quoining in small tufa blocks). Some later opus latericium and vittatum can be seen.

There is an ornamental brick entrance on the Cardo degli Aurighi. The doorway is 1.90 wide. From the threshold can be deduced that the doors were shut from the inside. The entrance is framed by brick columns supporting a brick pediment. A staircase next to the entrance led to the first upper floor.

To the right of the main entrance is a small secondary door, leading to the understairs. In the jambs are travertine blocks used for barring the entrance. It is the same system that was employed in the Warehouse of Epagathus and Epaphroditus (I,VIII,3). In one jamb was a plain hole, in the other a hole above which is a groove. Behind the latter hole is a small hole. A bar was lodged first in the plain hole and then dropped into the grooved one. There must have been a locking system at the end of the bar, whereby a bolt could be shot into the second smaller hole and secured, probably by a padlock.

Two narrow corridors can be accessed from a central court paved with opus spicatum. In the back wall of the court is a large, semicircular wall-niche. Two travertine consoles must have supported columns and entablature. On either side of the corridors are rows of three rooms. Above the doors to the rooms are small, rectangular windows. High up in the back wall of many rooms is a splayed slit window. In the side walls of some rooms are small, square windows, set even higher. In the corner of some of the rooms, in the back wall, is a small L-shaped slot, running horizontally from the wall and then vertically upwards. Presumably wooden shelves were inserted, or something very similar.

The warehouse obviously served local needs only. Unfortunately there is not a single clue about what was stored inside.
