Monopolise an area where spectators sit in GAA HQ (5)

I believe the answer is:

hogan

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

'area where spectators sit in gaa hq' is the definition.
I can't tell whether this defines the answer.

'monopolise an' is the wordplay.
'monopolise' becomes 'hog' (I've seen this in another clue).
'hog'+'an'='HOGAN'

Can you help me to learn more?

(Other definitions for hogan that I've seen before include "strong liquor" , "American golfing great" , "Eath-roofed hut" , "golfer, once" , "Log hut" .)

I've seen this clue in The Irish Times.
