City with a view of Vesuvius (6)
I believe the answer is:
naples
'city with a view of vesuvius' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for naples that I've seen before include "Major Italian city south of Rome" , "Mediterranean city" , "Port near to Vesuvius" , "Italian city of the planes" , "See it and die, they say" .)
