Metropolis of Pergamon
The Metropolis of Pergamon () was an ecclesiastical territory (diocese) of the Ecumenical Patriarchate of Constantinople in western Asia Minor, modern Turkey. Christianity in the city of Pergamon (modern Bergama), was introduced already from 1st century AD, while the local Christian community comprised one of the seven Churches of Asia mentioned at the Book of Revelation, written by John of Patmos. The bishopric of Pergamon was twice promoted to a metropolis: during the 13th–14th centuries, as well as for a short period in 1922. Today the "Metropolis of Pergamon and Adramyttium" is the see of a titular metropolitan.

The sanctuary was entered through a Propylon from the east, which led to a courtyard surrounded by stoas on three sides. In the centre of the western half of this courtyard, stood the Ionic temple of Demeter, a straightforward Antae temple, measuring 6.45 x 12.7 metres, with a porch in the Corinthian order which was added in the time of Antoninus Pius. The rest of the structure was of Hellenistic date, built in local marble and had a marble frieze decorated with bucrania. About 9.5 metres in front of the east-facing building, there was an altar, which was 7 metres long and 2.3 metres wide. The temple and the altar were built for Demeter by Philetaerus, his brother Eumenes, and their mother Boa.
