Festival — it lifted a Roman province (7)

I believe the answer is:

galatia

'roman province' is the definition.
(province of the Roman Empire)

'festival it lifted a' is the wordplay.
'festival' becomes 'gala' (a gala is a festival or party).
'lifted' is a reversal indicator (going up in down clue).
'it' written backwards gives 'ti'.
'gala'+'ti'+'a'='GALATIA'

I've seen this clue in The Guardian.
