Mosynopolis (Greek: Μαξιμιανούπολις - Μοσυνόπολις, Bulgarian: Месинопол), known in late Antiquity as Maximianoupolis, was a Byzantine town in Thrace located on the Via Egnatia near the modern Greek city of Komotini. The town was destroyed by the Bulgarian tsar Kaloyan in 1207[1] after his victory over the Latin Empire in the battle of Mosynopolis. The monk Ephrem[2] says that the city had been taken in 1190 by Frederick I, Holy Roman Emperor.
The episcopal see was a suffragan of Trajanopolis in Rhodope.
A single bishop is known, Paul, who assisted at the council of 878, which re-established Photius.[3] The see is mentioned in the Notitia of Leo the Wise, about 900[4]; in that for 940[5]; in that for 1170 under the name of Misinoupolis[6].
Mosynoupolis remains a Roman Catholic Church titular see, sometimes cited by the Italian name Mosinopoli.[7]
