In addition to the worship area of the Provincial Forum complex, Tàrraco had other temples, which we know of through inscriptions, coins and written sources.

We know of the Temple of Augustus from coins minted in Tarraco and the writings of Tacitus (who tells us that authorization was given for its construction in the year 15 AD). It was long thought to have been located in the Provincial Forum. However, various factors now point to the possibility of it being in the Colonial Forum. These factors include the chronology of the Provincial Forum, the evidence of various inscriptions related to the Imperial cult reused in the area of the early-Christian Necropolis, near the Colonial Forum, and the discovery in the area of a collection of Imperial statues.

Various elements tell us of other temples in Tarraco, although at present we do not know where they were located. The two votive altars found in this room are an example.

One contains a dedication to a builder called Quintus Attius Messor, who, at his own expense, painted and restored the exedra and facade of the, at that time, rather deteriorated Temple of Minerva.

The inscription on the other refers to a person called Baba who took part in the construction of the Temple of Tutela. There are also several fragments of relief, possibly part of a trophy, although unfortunately we do not know their origin
