Carsulae

Carsulae is an open archaeological landscape in the Comune di Terni where a long stretch of the ancient Via Flaminia still organizes the remains of a Roman town. You move between road, forum, basilica, temples, theater, amphitheater, baths, tombs and a medieval church, and that relationship is the whole point: public, sacred, civic and funerary spaces make sense because they still share one piece of ground.^1,2

The site is a state cultural site within the Musei Nazionali di Perugia, and it lies in the territory of Terni, near San Gemini.^3,4,5,1

The story starts with the Via Flaminia. The road was built through this area by about 220 to 219 BCE, and it was the principal condition for Carsulae’s growth. The site itself was well exposed, with fertile farmland and springs, which made it a natural place for a town.^2,6

The town itself is a little later. The urban center was in place by the end of the second century BCE, and the Republican phase is known mainly from inscriptions and limited structural remains beneath later works.⁶

Carsulae took the monumental form most visible today in the Augustan period, when it reached its greatest splendor, became a municipium governed first by duoviri and then by quattuorviri, and enrolled its citizens in the Clustumina tribe. It stayed a thriving, lively center at least until the early fourth century CE. The urban stretch of the Flaminia served as the main north to south axis, and it still preserves limestone paving, sidewalks in places and drainage channels.^2,6,1

The western branch of the Flaminia, the one through Carsulae, lost traffic to the eastern route through Narnia, Interamna Nahars (the ancient Terni) and Spoletium. The town also had no defensive walls, and a strong earthquake collapsed some of the sinkholes on which many public and private buildings stood, leaving the site inhospitable.^6,2,7

Carsulae was definitively abandoned between the end of the fourth and the beginning of the fifth century CE.⁶

Start on the paved road and follow its line. The trapezoidal forum lies on the west side of the Flaminia. Two small quadrifrons arches marked the entrances from the road, part of the square carried pink marble paving, twin temples stood to the south, and apsidal public rooms ran along the north. Julio-Claudian honorific fragments from this zone include a portrait head of Claudius.²

Across the road stands the basilica, a large apsidal building with three aisles and the bases of its internal columns still legible. Here "basilica" means a Roman civic hall, not a Christian church.²

Excavations have uncovered a large residence facing the forum, dated to the late first century BCE. The plan includes reception rooms, peristyles and water features, and a private bathing sector. A second phase adds a heated bath complex (frigidarium, tepidarium and calidarium) and further rooms with large mosaic floors. It gives the public square a domestic counterpart and shows how wealthy townspeople lived beside the forum.^8,9

A paved street leads east from the Flaminia to the entertainment district. The theater's seating rests on vaulted rooms, while the amphitheater was built using a natural sinkhole. Their shared alignment suggests coordinated planning, but each kept its own role.^2,6

A small colonnaded building near the theater is possibly a palaestra, and a long, multi-room cistern stands near the amphitheater. South of the center lie the partly excavated public baths, where floor mosaics were found. Drainage channels beside the Flaminia and several cisterns serving major buildings show that water was managed deliberately.^2,8,1

At the northern approach, the Arch of San Damiano survives as part of a structure that originally had three openings, with a concrete core faced in travertine slabs. Beyond it, monumental tombs line the road outside the ancient urban limit, one of them associated with the Furii family.^2,6

The medieval church next to the forum was built with reused Roman material on an ancient building. It appears as San Damiano and as Santi Cosma e Damiano, and it housed a small convent of nuns. Its fabric shows how later communities reused an older built landscape.^1,2,3

The Umberto Ciotti Visitor and Documentation Center stands at the entrance and holds a small display of archaeological material from the site.^1,10

Digging and discoveries here are documented from the sixteenth century, with intensive campaigns from 1951 to 1972 and research continuing afterwards. The plan you walk is therefore the sum of many excavation and conservation episodes, and large areas remain only partly investigated. Early finds include a sarcophagus, an inscription, a funerary cippus and a cistern.^2,3,11
