Here are the main GAA grounds in each of the 32 counties of Ireland, as well as the secondary grounds in Dublin and Cork. Only 4 are in hi-res (Croke Park and Parnell Park in Dublin and Pairc Ui Chaoimh and Pairc Ui Rinn in Cork). Even in lo-res most of the stadia are easy enough to spot. A few were trickier and needed a bit of googling to help pin-point them. There are a couple that I couldn't accurately locate (e.g. Newry) and I've just taken a "best guess" approach to these. Feel free to point out any inaccuracies.
