Augustopolis in Palaestina was a city in the Roman province of Palaestina Tertia, whose capital was Petra.
It corresponds to the site of Adhruh in modern-day Jordan.
One named John took part in the Council of Ephesus of 431.
Another of the same name was a signatory of the acts of the council called by Patriarch Peter of Jerusalem in 536 against Patriarch Anthimus I of Alexandria, a council attended by bishops of Palaestina Prima, Palaestina Secunda and Palaestina Tertia.
[1][2] No longer a residential bishopric, Augustopolis in Palaestina is today listed by the Catholic Church as a titular see.
