The Diocese of Zella (Latin: Dioecesis Zellensis) is a suppressed and titular see of the Roman Catholic Church.
[1][2] The diocese of Zella, is located in today's Tunisia.
During the Roman Empire the Diocese was centered on a Roman town of the Roman province of Byzacena. During late antiquity the city had both a Donatist and Catholic congregation. These two both sent bishops to the Conference of Carthage of 411.[3][4]
Today Zella survives as a titular bishopric and the current archbishop, personal title, is Angelo Acerbi, who was already the prelate of the Order of Malta's military sovereign.
