The portico with a faēade with eight pillars on the
west side is commonly know as the Granary
of the Forum. In reality it is actually a cereal and legume market.
The building's front has
eight openings. The interior walls do not have traces of decorations, a
sign that in 79 A.D. the building was not finished. Today it is used as
an archeleological warehouse. Amongst the most important finds stored
here are: various types of amphorę; casts of dead people, trees and
trunks; and tufa sculptures such as the Relief
of Issius, the pediment with Dionysius
and Ariadne from the Sanctuary
of Sant'Abbondio, and the image of the Thracian
gladiator.
