Croke Park is the home of the GAA. Gaelic games such as Hurling and Gaelic Football have been played here for many years.
It has undergone a huge renovation project over the years which makes it one of the most modern satdiums in Europe and the fourth largest.
One area of the ground is smaller than the rest.It is called Hill 16 which was originally made from some of the damaged rubble of O'Connell Street after the uprising of 1916.
In the GAA Musuem you can see the story of the Irish uprising and how the playing of Gaelic games developed.
In recent years,Football and Rugby have been played here during the renovation of the Landsdowne Road Stadium.
As you can see in the pictures,the pitch is covered up following the recent Republic of Ireland v Bulgaria game - it hadn't been snowing!
