Synada (Phrygia, Asia Minor - modern Şuhut, at 26 km to the south of Afyon Karahisar) was Christianised in ancient times. Its bishops are attested from the third century, and it was a metropolis in a region where heresies were rampant. Although poor and situated in an unproductive region, the metropolis seems to have survived as late as the fourteenth century.
