Nemea is an ancient site in the northeastern part of the Peloponnese, in Greece. It is famous in Greek myth as the home of the Nemean Lion which was killed by the hero Heracles. It is also known as the place where the infant Opheltes, lying on a bed of parsley, was killed by a serpent while his nurse fetched water for the Seven (http://en.wikipedia.org/wiki/Seven_Against_Thebes) on their way from Argos to Thebes. The Seven founded the Nemean Games in his memory, and the crown of victory was hence made of parsley and the judges wore black robes as a sign of mourning.
The stadion has recently been discovered. It is notable for its well-preserved vaulted entrance tunnel of about 320 BC with ancient graffiti on the walls.
