Elefsina

Elefsina is best known for having been the site of the Eleusinian Mysteries, the most famous religious center of ancient Greece. It was here that Heracles was initiated in the Eleusinian Mysteries so that he could learn how to enter and exit the underworld alive, to be able to kill the dog of the Underworld, Cerberus, one of his 12 tasks.

It was also the birth place of Aeschylus, one of the three great tragedians of antiquity.
