The large hall (84 x 38 m.) has an inclined floor and a small chamber opening to the left end; one of its niches is called the "liknon" of Zeus. A larger chamber (25 x 12 m.) formed on the right side is divided into two parts: one has a small pool, and the other a very impressive stalactite, known as "the mantle of Zeus". Inside the main chamber had been deposited many offerings, mostly bronze figurines and sheets (1, 2), daggers, arrowheads, and double axes.
