Forum Boarium
The Forum Boarium was the cattle market of ancient Rome, occupying level ground near the Tiber between the Capitoline, Palatine, and Aventine hills. As the site of Rome’s original docks and adjacent to the Pons Aemilius — the earliest stone bridge across the Tiber — the forum experienced intense commercial activity from the city’s earliest centuries. Today the area contains two of Rome’s best-preserved ancient temples: the circular Temple of Hercules Victor and the rectangular Temple of Portunus.

Overview
The Forum Boarium was the cattle market and commercial forum of ancient Rome, located on a level area near the Tiber between the Capitoline, Palatine, and Aventine hills. It served as the city’s original docking zone and, adjacent to the Pons Aemilius — the earliest stone bridge across the Tiber — it saw intense commercial activity for centuries. The forum gives its name to today’s Piazza Bocca della Verità, one of Rome’s most atmospheric open spaces.
History
The Forum Boarium is among the oldest continuously occupied areas of Rome, with evidence of settlement and trade dating to at least the 7th century BC. Its proximity to the Tiber ford and later the Pons Aemilius made it the natural heart of early Roman commerce. Religious and civic monuments accumulated over centuries, including temples to Hercules, Portunus, Fortuna, and other divinities associated with commerce and navigation. The area remained commercially vital through the Imperial period before giving way to medieval and Renaissance development.
What you see
The most prominent surviving monuments are the Temple of Hercules Victor — a perfectly preserved circular peripteral temple — and the rectangular Temple of Portunus nearby. The medieval church of Santa Maria in Cosmedin, home to the famous Bocca della Verità (Mouth of Truth), occupies the ancient site of the Statio Annonae. The whole area retains the irregular topography and layered chronology typical of central Rome.
Cultural significance
The Forum Boarium represents one of the oldest layers of Rome’s urban history, preserving some of the Republic’s most intact temple architecture. Its combination of ancient monuments, medieval churches, and Renaissance surroundings makes it an exemplary site for understanding the palimpsest nature of the Eternal City. The Bocca della Verità alone draws hundreds of thousands of visitors annually.
