maypole

I'm a little stuck... Click here to teach me more about this clue!

'fixture at spring festival?' is the definition.
I can't tell whether this defines the answer.

'tree european' is the wordplay.
'tree' becomes 'may' (I've seen this in other clues).
'european' becomes 'pole' (someone from Poland).
'may'+'pole'='MAYPOLE'

Can you help me to learn more?

(Other definitions for maypole that I've seen before include "Decorated springtime post" , "Some English dance around it on 1st May" , "Centre of ribbon dance" , "Feature of traditional spring festivities" , "Something danced round" .)

I've seen this clue in The Times.
