The Forum Boarium

The Forum Boarium (Italian: Foro Boario) was ancient Rome’s cattle market, situated on flat land near the Tiber River between the Capitoline, Palatine, and Aventine hills. Positioned near Rome’s original docks (Portus Tiberinus) and the Pons Aemilius, the first stone bridge over the Tiber, it was a bustling commercial hub.

Historically, the Forum Boarium was a religious center housing significant temples such as the Temple of Hercules Victor and the Temple of Portunus, along with the Ara Maxima, a large altar. According to legend, Hercules brought Geryon’s oxen to this area, only to have them stolen by the giant Cacus. After defeating Cacus, Hercules was venerated by Rome’s early inhabitants, who dedicated an altar to him, now preserved in Santa Maria in Cosmedin church.

The Forum Boarium hosted Rome’s first gladiatorial contest in 264 BC, organized by Marcus and Decimus Junius Brutus Scaeva as a funerary gift. In 215 BC, Romans performed human sacrifices here to appease the gods during a crisis, as documented by Livy.

Architecturally, the Temple of Hercules Victor is a circular marble building from the 2nd century BC, featuring Corinthian columns around a cylindrical cella. The Temple of Portunus, built between 100-80 BC, is rectangular with Ionic columns and a prominent portico. Both temples were later converted into Christian churches.

In the late 1990s, restoration efforts by Rome’s archaeological authorities and the World Monuments Fund preserved these temples and enhanced the site’s landscaping, although the Arch of Janus remains unrestored.
