The Temple of Hercules Victor | Rome

The Temple of Hercules Victor is an ancient circular edifice located in the Forum Boarium, the former cattle market of Rome, situated between the Tiber River and the Circus Maximus.

Visual Characteristics

The temple is a monopteros-a circular structure-surrounded by 20 Corinthian columns (19 of which are original). It is built of white Pentelic marble, making it one of the earliest marble buildings in Rome. The structure features a central cella and a conical roof, which is a later tile addition. Due to its shape, it was long misidentified as a Temple of Vesta.

Historical Origin

Dating to the late 2nd century BC (approx. 120 BC), it is the oldest surviving marble temple in Rome. It was likely commissioned by a wealthy Roman merchant, Marcus Octavius Herrenus, to honor Hercules, the patron of olive oil merchants. In the 12th century, the temple was converted into a church (Santo Stefano delle Carrozze), which ensured its preservation through the Middle Ages.
