Hebridean island famed for its Abbey (4)

I believe the answer is:

iona

(Other definitions for iona that I've seen before include "early Christian centre" , "Scottish island from where Christianity spread in 563 AD" , "Hebridean island associated with St Columba" , "St Columba's island of the Inner Hebrides" , "Scots monastery isle" .)

I've seen this clue in The Guardian.
