The Ancient City of Thyateira is an ancient city located in the Akhisar district of Manisa and is of great importance in terms of Christian history. One of the 7 churches mentioned in the Bible, the Thyateira Church was an important center in the early Christian period. The ruins of the church are located in the city center of Akhisar today and offer important clues to the past to its visitors with its columns, stonework and architectural remains from the early Byzantine period. Thiatira was also the scene of a battle during the Roman Empire. Thyateira was an important trade and production center during the Roman period because it was located on trade routes. This city, especially famous for its dye production and fabric trade, was known for its purple fabrics. In 366 AD, the Cilician commander Procopius, who rebelled for the Roman throne and attacked with the legions under his command, and the troops of Valens, the brother of Valentinian I, the heir to the Roman throne, met in the city of Thiatira. At the end of the battle, which went down in history as the Battle of Thyatira, Valens' forces prevailed and Procopius, who was captured, was executed. The Necropolis (ancient burial ground), an important part of the ancient city, is one of the oldest burial grounds in the Akhisar area. Sarcophagi, tombstones and reliefs from the Lydian, Roman and Byzantine periods were found during the excavations here. The tomb structures provide important information about the religious beliefs and burial traditions of the people living at that time.
