Pergamum (also known as Pergamon or Pergamos) was the third of the seven churches to receive a letter from Jesus Christ (Revelation 2.12-17).
The ancient city of Pergamum was built on a huge rocky hill, which towered high above the plain of the Caicus River. The city is viewed from the Sacred Way or Via Tecta, the colonnaded street that came from the Asclepium and led to the Citadel of Pergamum.
