Cuzco attraction (5)
I believe the answer is:
ruins
'cuzco attraction' 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 "Wrecked buildings" , "Derelict remains of building" , "Wrecks" , "Damages irreparably" , "Broken-down remnants" .)
