Pliny the Elder
(5.20) says that the town was a colony of Augustus;
inscriptions prove that the Colonia Julia Augusta was
founded by veterans of the Seventh Legion, just as were
the towns of Saldae (Bedjaia) and Tubusuctu (Tiklat)
in the valley of the Soumam. This undoubtedly occurred
at the time when Octavius controlled Mauretania before
that region was once again put in the hands of Juba II.
The small, picturesque village of Azeffoun is located
on the plateau that dominates the site of Port-Gueydon.
In it one can still see some remains of buildings, in
particular a bath building. Concerning the identification of the site, see also under the entry
