Smyrna

myrrh, an ancient city of Ionia, on the western coast of Asia Minor, about 40 miles to the north of Ephesus. It is now the chief city of Anatolia, having a mixed population of about 200,000, of whom about one-third are professed Christians. The church founded here was one of the seven addressed by our Lord (Rev 2:8-11). The celebrated Polycarp, a pupil of the apostle John, was in the second century a prominent leader in the church of Smyrna. Here he suffered martyrdom, A.D. 155.
