Indian mausoleum (3,5)
I believe the answer is:
taj mahal
'indian mausoleum' 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 of Mogul empress" , "Famous mausoleum in Agra in northern India" , "Agra wonder" , "Mausoleum at Agra built in memory of emperor's favourite wife" , "Agra memorial" .)
