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 Altar
The German Empire, which subsidized the excavation not least for reasons of prestige, quickly began to monopolize the altar and other archaeological relics. The "Jubilee Exhibition of the Berlin Academy of Arts" in May and June 1886 devoted a 13,000 square meter site to archaeological acquisitions from recent excavations in Olympia and Pergamon. But since the Greek government had not given permission to export art treasures, no finds from Greece could be shown there. Instead, a "Temple of Pergamon" was constructed. With a true-to-scale model of the western side of the altar base containing selected copies of the frieze — including the Zeus and Athena group from the eastern frieze — an entrance area for a building was erected which resembled the Zeus temple in Olympia. Part of the exhibit was a model of the city of Pergamon in the 2nd century AD reflecting the state of knowledge at that time.
