Rectangular platform to the NW of the Sanctuary, containing a statue of Dionysos flanked by two actors impersonating Paposilenoi (now in the Museum). On either side of the platform, a pillar supports a huge phallus, the symbol of Dionysos. The southern pillar, which is decorated with relief scenes from the Dionysiac circle, was erected in ca. 300 B.C. by a Delian named Karystios in order to celebrate a victorious theatrical performance sponsored by him.
