It was probably built in the II century AD outside the city’s boundary walls, next to the Tessino stream. Only a few traces of the ancient structures remain, because of the various devastation episodes faced: already in the VI century, Totila’s Goths turned the amphitheatre into a garrison, then, in the XIII century, the ambulatory’s arches became artisans’ shops, while above the cavea and the arena, the church of San Gregorio minore and the Monastero del palazzo started to be built. At the end of the XIV century the whole building was in practice dismantled, as it became a quarry for the construction of the Rocca Albornoziana. Hagiography in the Middle Ages indicated the amphitheatre as martyrdom and killing place of Spoletan martyrs and saints.
At present, the complex is not visitable.
