The city of Paris (4)
I believe the answer is:
troy
'the city of paris' is the definition.
(Paris was a hero from Troy in mythology)
This is the entire clue.
(Other definitions for troy that I've seen before include "City destroyed" , "Where beautiful Helen came from" , "City impacted by long-term investment" , "Iliad siege city" , "Legendary ancient city of northwest Anatolia" .)
