I got it eventually, but by sheer luck
Only the smart kids took geometry, not me.
The (completely silly) argument people like to have is about which modern nation-state gets the rights to use the name of the ancient kingdom and region.
I kinda feel cheated.
Made me smile!
BTW if you didn't smile, watch this!
The acropolis clue could be so easily separated from the connection to Athens - it's just a citadel on an elevated area, and put after the Parthenon clue would be easy to make it clear. Many if not most Greek city states had one.
Would you enjoy the clue, "Natural flowing watercourse passing through London" (ANS: RIVER)
