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 80 m long and 55 m wide 'Lower Agora' was built under Eumenes II and was not significantly altered until Late Antiquity. As with the Upper Agora, the rectangular form of the agora was adapted to the steep terrain. The construction consisted in total of three levels. Of these the Upper Level and the 'Main Level' opened onto a central courtyard. On the lower level there were rooms only on the south and east sides because of the slope of the land, which led through a colonnade to the exterior of the space. The whole market area extended over two levels with a large columned hall in the centre, which contained small shop spaces and miscellaneous rooms.
