Home of the Bolshoi Ballet (6)
I believe the answer is:
moscow
'home of the bolshoi ballet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for moscow that I've seen before include "Russian city" , "Olympic city, 1980" , "Kremlin location" , "Bolshoi Ballet base" , "City of 13" .)
