Pergamon Altar
Already Attalos I began to remodel the acropolis of Pergamon. In the course of time the original structures were augmented by a Dionysus temple, a theater named after Dionysus, a heroon, an upper agora for the city, and the great altar known today as the Pergamon Altar. There were also several palaces, and a library in the Athena sanctuary.
