Traianopolis, Trajanopolis, Tranopolis, or Tranupolis (Greek, Modern (1453-);: Τραϊανούπολις) was a Roman and Byzantine city in Phrygia Pacatiana Prima.
Trajanopolis has been variously identified; Radet[1] locates it at Çarikköy, about three miles from Giaurören towards the south-east, on the road from Uşak to Suzusköy, a village abounding in sculptures, marbles and fountains, where the name of the city may be read on the inscriptions. However, Ramsay[2] continues to identify Trajanopolis with Giaurören. Modern scholars place it near Ortaköy.
The only Ancient geographer who speaks of Trajanopolis is Claudius Ptolemy,[3] who wrongly places this city in Greater Mysia (another region of Asia Minor). It was founded about 109 by the Grimenothyritae, who obtained permission from Roman emperor Hadrian to give the place the name of his predecessor. It had its own coins. Hierocles calls it Tranopolis.[4]
In the Notitiae Episcopatuum, Traianopolis is usually called Tranopolis, and is mentioned as an episcopal see up to the 13th century, among the suffragans of Laodicea, the capital and Metropolitan see of the Roman province of Phrygia Pacatiana Prima.
Le Quien names seven bishops of Trajanopolis:
The bishopric of Trajanopolis is included in the Catholic Church's list of titular sees,[6] as the diocese was nominally restored in the 17th century as a titular bishopric, initially as just Traianopolis, renamed since 1933 Trajanopolis in Phrygia, thus avoiding confusion with its Thracian namesake (in Roman province Rhodope).
It is vacant, having had the following incumbents, of the lowest (episcopal) rank, with a singular archiepiscopal exception :
