Ancient temple, home to Greece's foremost Oracle (6)

I believe the answer is:

delphi

(Other definitions for delphi that I've seen before include "Home of the oracle on the slopes of Mount Parnassus" , "Where Apollo's most famous oracle spoke in Greece" , "Scene of Greek oracle" , "Ancient Greek city, site of famous oracle" , "Site of classical Greek oracle" .)

I've seen this clue in The Guardian.
