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.
Alexander Conze
In 1878 with engineer Carl Humann, he began excavation at Pergamon in Asia Minor, a project that lasted until 1886. With Wilhelm Dörpfeld, he started a second archaeological dig at Pergamon in 1900. At Pergamon, Conze and Humann uncovered one of the greatest archaeological treasures of Hellenistic civilization, the Pergamon Altar, which today is housed at the Pergamon Museum in Berlin.
