The Temple of Vespasian and Titus is located in Rome at the western end of the Roman Forum between the Temple of Concordia and the Temple of Saturn. It is dedicated to the deified Vespasian and his son, the deified Titus. It was begun by Titus in 79 after Vespasian's death and Titus's succession. Titus’ brother, Domitian, completed and dedicated the temple to Titus and Vespasian in approximately 87.
Throughout Roman history, there was an emphasis on increasing the fame and glory of a family name, often through monuments commemorating the deceased. Therefore, the temple was constructed to honour the Flavian Dynasty, which comprised the emperors Vespasian (69–79), Titus (79–81), and Domitian (81–96). Historians question whether or not Titus and Domitian had a good relationship; however, Domitian ensured the deification of his brother into the imperial cult in order to exalt the prominence of the Flavian name. Titus and Vespasian were each deified through the ceremony of apotheosis. In doing so, tradition guaranteed that Roman citizens and subjects would honour Vespasian and Titus (or at least honour their genius) as Roman deities. This imperial cult worship was as much a sign of allegiance to the emperor of Rome, or as a political and diplomatic gesture, as it was a formal religion.
The Temple of Vespasian was in the Corinthian order, hexastyle (i.e. with a portico six columns wide), and prostyle (i.e. with free standing columns that are widely spaced apart in a row). It was particularly narrow due to the limited space, measuring 33 meters long and 22 wide. In a constricted space between the temple and the Concord, a small, two-story vaulted room made of brick and concrete, and lined with marble, was built against the wall of the Tabularium, and apparently was dedicated to Titus.
