South of the imperial cult area are a series of tabernae that opened out onto the portico that surrounded the actual open area of the forum. The larger structure with an apsidal northern wall, at the western end of this row of tabernae is identified as the seat of the collegia of the Augustales.
Adjacent to that structure, on the west end of the forum, is the shrine of the lares publici. This structure was built in the late 2nd century CE, replacing an existing taberna. The raised area of the forum directly in front of these building also seems to be associated with it. Flanking the shrine are buildings that probably served as governmental offices.
