The Parthenon is dedicated to her (6)
I believe the answer is:
athena
'the parthenon is dedicated to her' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for athena that I've seen before include "wise but fierce goddess" , "Greek goddess of a capital city" , "Greek goddess of wisdom etc." , "One-time goddess" .)
