TRES TABERNAE. — Ancient diocese and station on the ancient Via Appia, 3 miles from Rome, according to the Itinerary of Antoninus; it is also mentioned by Cicero (Ad Atticum, I, 13, 1; II, 10; 13, 1).
When the faithful of the community of Rome learned that s. Paul had set out from Pozzuoli for Rome, they went to meet him; some went as far as Forum Appii, while others awaited him at T. T. (Act. 28, 15). It had a bishop named Felix as early as 313. In the Roman Synod of 492, the bishop Decius signed the acts. In 592, Pope Gregory, because of the desolation of the area after the Gothic siege, annexed the territory of T. T. to the diocese of Velletri (s. Gregorio Magno, Ep., II, 50; PL 76, 591–92). However, the bishop of T. T. reappears among those present at the Council of 769 and in later documents up to the year 868.
