Arco di Adriano (Arco Felice)

The Arco di Adriano, also known as Arco Felice, stands on the former line of the Via Appia at the edge of Santa Maria Capua Vetere. Built in brick and traditionally dated to around 130 AD, it marks the transition between the ancient city of Capua and modern Capua.

Why it matters

The arch belonged to one of the Roman world's most important roads. The Via Appia, extending from Rome through ancient Capua, became the UNESCO World Heritage property Via Appia. Regina Viarum in 2024. Its traditional association with Hadrian places it within the imperial history of the Appian Way.

What to notice

The brick gateway stands slightly askew from the present road. The municipal account attributes this angle to a shift of roughly 25 degrees in the road's alignment. Steps once fitted along the arcades allowed pedestrians to cross the structure. A marble plaque placed in 1860 bears a text by Luigi Settembrini commemorating the nearby Battle of the Volturno, adding a nineteenth-century layer of memory to the Roman monument.

Context and history

The arch is traditionally associated with Hadrian, who was known to spend time in Capua. The monument stood at the meeting point of ancient Capua and Casilinum, where it marked and celebrated traffic along the Appian Way. Over the centuries, later stairways and adjoining walls incorporated the arch into the developing town. It is protected as part of the historic centre of Santa Maria Capua Vetere.
