Saldae was an important port city [1] in the ancient Roman Empire, located at today's Béjaïa (in Kabylia, eastern Algeria).

It was generally a crossroads between eastern and western segments of Northern Africa, from the time of Carthage to the end of the Byzantine Empire from the continent.

A minor port in Carthaginian and in early Roman times, it was a border town between Rome and Juba, located to the east of the ancient Berber kingdoms.

Vestiges of the ramparts are visible at several places....Of the monuments which have been preserved or noted, particularly interesting are the remains of a temple underneath the church, built on the site of a mosque.

In the 3rd century AD, Gaius Cornelius Peregrinus, a decurion (town councillor) of Saldae, was a tribunus (military tribune, a commander at cohort level) of the auxiliary garrison at Alauna Carvetiorum, in northern Britain.

In the 11th century, it was refounded as Béjaïa (v.) by the Berber Hammadid dynasty, which made it their capital, and it became an important port and centre of culture.

A letter of Pope Gregory VII (1073–1085) exists, addressed to clero et populo Buzee (the clergy and people of Béjaïa), in which he writes of the consecration of a bishop named Servandus for Christian north Africa.
