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.
Hierapolis
Hierapolis was first excavated by the German archaeologist Carl Humann during June and July 1887. His excavation notes were published in his 1889 book "Altertümer von Hierapolis". His excavations were rather general and included a number of drilling holes. He would gain fame for his later discovery of the Pergamon Altar, which was reconstructed in the Pergamon Museum in Berlin.
