Arco di Riccardo

At the edge of Trieste's oldest quarter, a Roman arch survives between later buildings. Its original purpose is uncertain, and popular tradition has connected its name with Richard the Lionheart, although no document links him to the monument.

Why it matters

The Arco di Riccardo is one of the best-preserved fragments of Roman Tergeste still standing in the modern city. The single-arched monument is framed by pilasters with Corinthian capitals. Its western pier was uncovered in 1913, while the eastern pier remains partly enclosed within a later building, leaving the Roman structure visible amid the changing street plan.

What to notice

The arch stands on the north-western slope of San Giusto hill. Its rounded opening and Corinthian pilasters mark the scale and form of the monument. The setting is asymmetrical: the western pier is freestanding, while the eastern one is incorporated into a neighbouring structure.

Context and history

Roman Tergeste grew around San Giusto hill, where defensive walls were built in 33–32 BCE under Augustus. The arch is later: the regional heritage catalogue dates it to about the middle of the first century CE and interprets it as an addition to the wall circuit after the walls had lost their defensive role. Other interpretations propose a monumental passage between city quarters or an entrance to a nearby sanctuary of Magna Mater. Its name has also been associated with the medieval office of a ricario or with the word cardo, one of the principal axes of a Roman city. Over time buildings enclosed much of the arch; the 1913 excavations freed its western pier.
