Capital with the Norsk Folkemuseum (4)
I believe the answer is:
oslo
'capital with the norsk folkemuseum' 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 "Capital of Norway" , "Nordic capital" , "Capital in throes of go-slow" , "Former Christiania" , "Location" .)
