Historical Background

The arch was built between 114 and 117 AD to celebrate Trajan and the opening of the Via Traiana, a shortcut of the Via Appia to Brindisi. During the Lombard period, it was incorporated into the city walls as Porta Aurea, saving it from the centuries. In 1850, Pope Pius IX had the surrounding houses demolished to isolate it. Since 2024, it has been part of the UNESCO site “Via Appia. Regina Viarum”.

The Richness of the Reliefs

What makes this arch unique are the bas-reliefs, incredibly well-preserved. On the facade facing the city, you see scenes of peace: distribution of grain, founding of colonies. On the outer side, instead, military triumphs and subdued provinces. In the archway, the panels of the Sacrifice for the Via Traiana and the Institution of the Alimenta, the program of aid to poor children, stand out. Every detail is a piece of Roman history.

The arch is located on Via Traiano, just steps from downtown. No opening hours, no ticket needed—you see it as soon as you arrive. The Parian marble shines especially in the early morning or at sunset, when the light brings out the reliefs. Bring binoculars to catch the details up high—the tauroctonic Victories, the season spirits, and the dedicatory inscription from the Senate and People of Rome. And if you want to learn more, the nearby Church of Sant’Ilario houses an interactive video museum on Trajan.

When to Go

I recommend late spring or early autumn, when the light is warmer and the days are long. Early morning (around 8 a.m.) offers a low-angle light on the ridges, perfect for photos. But in the evening, when illuminated, it has its own charm. Avoid the midday hours in summer: the sun beats down hard and the contrast is blinding.

Nearby

Just a few steps away, the Roman Theatre (inaugurated in 126 AD) makes you feel like an ancient spectator. And the Church of Santa Sofia, a Lombard UNESCO heritage site, with its star-shaped plan, is a gem an 8-minute walk away. If you have time, the Museo del Sannio (inside Santa Sofia) tells the local history from prehistory.

💡 Did You Know…?
During the Middle Ages, the arch was incorporated into the city walls and renamed Porta Aurea. In 1850, Pope Pius IX ordered the demolition of surrounding houses to highlight it. It has withstood earthquakes and wars; the 2001-2002 restoration brought it back to its former glory. Today, at night, the illuminated arch serves as the backdrop for city celebrations, such as Benevento Calcio’s promotion to Serie A in 2020.
