Messad

Messad (sometimes Messaad; Arabic: مسعد) is a town in Algeria. It was the Roman Castellum Dimmidi. It is about 290 km (180 mi) south of Algiers. During the Roman period it was known as Castellum Dimmidi after the Romans under emperor Septimius Severus seized the settlement.[2] It is unclear if the second part of the name, Dimmidi, was a native name transliterated into Latin, or a new name given by the Romans.
