Acropolis sight (5)
I believe the answer is:
ruins
'acropolis sight' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ruins that I've seen before include "Damages irreparably" , "Derelict buildings" , "Collapsed, disintegrated buildings" , "Wrecked buildings" , "Spoils" .)
