Mausoleum at Agra (3,5)
I believe the answer is:
taj mahal
'mausoleum at agra' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for taj mahal that I've seen before include "... mausoleum raised by ..." , "Mausoleum at Agra in memory of a Mogul wife" , "Mausoleum at Agra built in memory of emperor's favourite wife" , "Famous Indian mausoleum in Agra" , "Agra memorial" .)
