When most people think of the world's great stadia, they probably have in mind the Giants Stadium in New York, Ellis Park in Johannesburg or Wembley in London.
These great theatres of entertainment are all home to professional and global sports such as American football, rugby union or soccer.
Yet there is a stadium in Dublin, which is just as large and iconic but is home to purely amateur and far less well-known sports such as hurling and Gaelic football.
With a capacity of 82,000, Croke Park oozes sporting as well as political history and it's the pride and joy of the GAA (Gaelic Athletic Association) - a volunteer organisation, which doesn't pay its top players anything.
