Pergamon
Pergamon's other notable structure is the great temple of the Egyptian gods Isis and/or Serapis, known today as the "Red Basilica" (or "Kızıl Avlu" in Turkish), about south of the Acropolis at (39 7' 19" N, 27 11' 1" E). It consists of a main building and two round towers within an enormous "temenos" or sacred area. The temple towers flanking the main building had courtyards with pools used for ablutions at each end, flanked by stoas on three sides. The forecourt of the Temple of Isis/Sarapis is still supported by the Pergamon Bridge, the largest bridge substruction of antiquity.
Pergamon
Settlement of Pergamon can be detected as far back as the Archaic period, thanks to modest archaeological finds, especially fragments of pottery imported from the west, particularly eastern Greece and Corinth, which date to the late 8th century BC. Earlier habitation in the Bronze Age cannot be demonstrated, although bronze Age stone tools are found in the surrounding area.
