Ain Zana
# Ain Zana

Ain Zana (Aïn-Zana) is a town and commune in Souk Ahras Province in north-eastern Algeria. It is the site of Diana Veteranorum, a former ancient city and bishopric in Numidia. It is now the Latin Catholic titular see, Diana.

## History

Diana was important enough in the Roman province of Numidia to become one of the many suffragan bishoprics no later than mid third century AD, yet was to fade.
