The seat of the bishopric was the ancient city of Siga which is identifiable with the ruins of Takembrit on the Mediterranean coast in modern Algeria. Siga was a major port city in the ancient Kingdom of Numidia, and during the Second Punic War, the kings of Siga sided with Rome.[4][5] The city got some importance inside the Roman Africa, especially with African emperors Septimius Severus and Caracalla. With the Arab conquest, during the second half of the seventh century, disappeared all references to Siga in documented history.[6][7]
