Ancient city of Attica, Greece, 12 mi north west of Athens.
Through ancient times it was the seat of the Eleusinian Mysteries. There was a large temple to Demeter. The Eleusinian games, also held there, were not connected with the mysteries.
Excavation of the cemetery found graves that date from the 7th and 8th cent. B.C. The temple and a type of theater with rock-cut seats for about 3,000 spectators were uncovered near the modern village of Eleusis.
