I don't know... democracy?

Cradle of what we call today Western civilization

Philosophy, science, international.

Theatre? (Both the physical form of amphitheatre and all genres of plays).

Theater, philosophy, mathematics, medicine, etc.

Evidence that there were great civillisations thousands of years ago that affects the western world today.

Ancient Greece is first defined by the territory inhabited by Greeks, no matter how far is it, who is the lord of the land, is Greece. It's a community, more than a country.
