Trapezopolis (Ancient Greek: Τραπεζόπολις) or Trapezoupolis (Τραπεζούπολις) was a city of ancient Caria, and later in the late Roman province of Phrygia Pacatiana Prima.
At an earlier stage, Trapezopolis was part of Caria, as reported by Ptolemy[1] and Pliny the Elder, but by the time of Socrates of Constantinople, Hierocles and the various Notitiae Episcopatuum it belonged to Phrygia Pacatiana.
[2] Its site is located near Boli in Asiatic Turkey.
[3][4] The bishopric of Trapezopolis was a suffragan of Laodicea, the capital and metropolitan seat of the province of Phrygia Pacatiana Prima.
It is mentioned as a residential see until the 13th century and is now included in the Catholic Church's list of titular seats.
