moles of the Roman town's commercial harbor and the line of its military harbor; both had been mostly artificial and have silted up since antiquity. Louis Carton and AbbéLeynaud rediscovered the Christian catacombs in 1904; the tunnels extend for miles through small subterranean galleries filled with Roman and Byzantine sarcophagi and inscriptions. Ruins In addition to the Punic walls, Roman harbors, and Byzantine catacombs, there are ruins of the Byzantine acropolis and basilica; the Roman horse track, cisterns, the theater; and a Punic necropolis. Religion As a major Roman city, Hadrumetum produced a number of Christian saints, including Mavilus during the regional persecutions of Caracalla's reign and the Bishop Felix and proconsul Victorian during the Vandals' efforts to forcibly convert their subjects to Arianism. From 255 to 551, the city was the seat of a Christian bishopric. The see was revived in the 17th century as a Catholic titular see.
