The name derives was the Telesterion of Eleusis, where every year took place the famous in the ancient world mysteries of Eleusis. Already in Mycenaean times was located on the site of a shrine in the form of a Megaron. Its final form was given to the temple by Iktinos and his successors in the 5th century BC: a square, 52 × 52 m measuring temple with a flat roof, which was supported by 6 × 7 Ionic columns, and a large interior with 6 doors which took about 7,000 visitors. On the walls there were circumferential rows of seats for spectators at the Mysteries. In the center was the Anaktoron ( ἀνάκτορον, "palace" ), the Holy of Holies, in which it was a small stone building, to which only the priests had access. In Anaktoron sacred objects of Demeter were kept.
