Roman Theater is the most obvious and impressive relic of ancient Philadelphia. The theater, which was built during the reign of Antonius Pius (138-161 CE), is cut into the northern side of a hill that once served as a necropolis—or graveyard. It is very similar in design to the amphitheater at Jerash, and can accommodate 6000 spectators. The theater is still used periodically for sporting and cultural events.
