Hi Antoine,
I write from Dublin Ireland, where there are many Rugby fields across the country. Our most famous is currently being rebuilt, however, for the time being, the main stadium is Croke Park, which is right in the city centre and holds in excess of 80,000 people. Across the country are many fields for rugby and Irish football, close to the sea, in the middle of farmland and right beside small towns and villages. Let me know if you would like us to source you some references, or perhaps you could email me a brief. Kind regards
