Munch Museum city (4)
I believe the answer is:
oslo
'munch museum city' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oslo that I've seen before include "Norway's capital city" , "Norwegian city, formerly Kristiania" , "Location" , "Capital in throes of go-slow" , "Northern capital of Czechoslovakia?" .)
