Vallitanus or Vallis was an ancient Roman–Berber colonia in Carthage, Tunisia.
The town is identified with ruins at Sidi Medien,[1][2] where are located the remains of a Roman theatre,[3][4] and a number of Roman inscriptions bearing witness to the town's name, and some local officials of the time can be found near the theatre.
[5][6] Roman Vallitanus was also the seat of an ancient bishopric under the metropolitan of Cartagine.
The bishopric ceased to function in the early 8th century with the arrival of Islam.
[8] The current bishop of Vallitanus is José Rafael Palma Capetillo, who replaced Jean-Michel di Falco Léandri.
