 A large grove, a Doric temple (remains of which survive), and a cave called the Charonium, were the seat of the oracle.Strabo noted that "The sick resort thither, and live in the village near the cave, among experienced priests, who sleep at night in the open air and direct the mode of cure by their dreams.The priests invoke the gods to cure the sick, and frequently take them into the cave, where they remain in quiet without food for several days.
