Aggar
Kairouan Governorate, Tunisia
Aggar was a town and bishopric (now titular) in the Roman province of Byzacena. One of two cities in the area, it left vast ruins that are now called (Henchir) Sidi Amara. These edifices are situated in the plain of Siliana, around 60 kilometres east of Maktar. A distinct Sidi Amara further north in Tunisia holds the ruins of the Ancient town of Avioccala, located in the Roman province of Africa Proconsularis.
