Iomnium was a Phoenician, Carthaginian, and Roman port on Algeria's Mediterranean coast at the site of present-day Tigzirt.


Iomnium is a latinization of the town's Punic name, which appears to have combined the elements ʾY (Punic: 𐤀‬𐤉‬) and ʾMN (𐤀‬𐤌𐤍‬), meaning "Strong Island"[1] or "Peninsula of Strength".[2] The same triliteral root can also mean "craftsman", "artisan", &c.[3]


Iomnium was located on a peninsula, with the civic buildings located at the end of its cape.


The town was established as a colony on the trade route between Phoenicia and the Strait of Gibraltar. It formed part of the Carthaginian Empire and served as the harbor for the fortress at Rusippisir (present-day Taksebt) 3 km (2 mi) to its east.[1]

It fell under Roman hegemony following the Punic Wars. Under Roman rule, Iomnium had the status of a native city (civitas)[4] in the province of Numidia. Excavation has revealed a moderately-sized Roman emporium.[5] It had a forum, temple, courthouse, and magistrates' office. Its Roman streets were laid out on a grid.[6] A public bath and ornamental mosaic have been found, with inscriptions and statues scattered around.[7]

It was conquered with the rest of the area around it during the late 7thcentury.

Identification of its ruins were long delayed by errors in its mention in the Tabula Peutingeriana,[8] which placed it "42 miles" west of Rusippisir instead of the actual distance of about 2 miles.[1] Iomnium, not Iol, is also probably the Ioulíou (Greek: Ἰουλίου) mentioned by the Periplus of Pseudo-Scylax, the present text probably representing a scribal error of the original name.[1]


Iomnium was the seat of a Christian bishopric in antiquity.[9] The ruins of a small basilica have been uncovered.[10] The building has three naves with galleries over the aisles. There was a baptistery of polyfoil plan to the northeast.

The diocese was revived by the Roman Catholic Church as a titular see.[11] The current bishop is Jaime Calderón Calderón.
