Trajanopolis has been variously identified; Radet 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 continues to identify Trajanopolis with Giaurören.
The only geographer who speaks of Trajanopolis is Ptolemy, 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.
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 province of Phrygia Pacatiana Prima.
