Site of the Taj Mahal (4)
I believe the answer is:
agra
'site of the taj mahal' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for agra that I've seen before include "Eastern city" , "North Indian city, former capital of the Mogul empire" , "City in India" , "Site of the Taj Mahal" , "Taj Mahal city" .)
