Taj Mahal locale (4)
I believe the answer is:
'taj mahal locale' 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 "Site of the Taj Mahal" , "Taj Mahal city" , "city founded in 1566" , "Taj Mahal location" , "Indian masterpiece" .)
