1952 Winter Olympics host (4)
I believe the answer is:
oslo
'1952 winter olympics host' 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 city, called Kristiania until 1924" , "Nordic capital" , "City in Norway" , "Former Christiania" , "foreign port" .)
