"Iliad" locale (4)

I believe the answer is:
troy
'iliad locale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for troy that I've seen before include "System of weights introduced by French" , "System of weights; ancient city in Turkey" , "Priam's city" , "Weight system - old city" , "System of weights for precious stones and metals" .)
