Pairs cool off in ancient place above Athens (9)
I believe the answer is:
acropolis
'athens' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for acropolis that I've seen before include "classical site" , "Imposing building" , "high point" , "Citadel of ancient Greece" , "Greek tourist spot" .)
