Health resort in European country (5)
I believe the answer is:
spain
'european country' is the definition.
(country in Europe)
'health resort in' is the wordplay.
'health resort' becomes 'spa' (spa can mean a health resort).
'spa'+'in'='SPAIN'
(Other definitions for spain that I've seen before include "European monarchy" , "ditto" , "Kingdom" , "Catholic country" , "European nation" .)
