10. Croke Park
Croke Park is the stadium where Ireland's two national sports, hurling and Gaelic football, are played. It is also the headquarters of the Gaelic Athletic Association (GAA), the sporting body responsible for these national games.
It is hard to belive that Croke Park is primarily designed for amateur sports - with a capacity of aroound 80,000, it is the fouth largest stadium in Europe.
But it's much more than merely a stadium: it has been described as the spiritual home of Irish cultural nationalism. Hurlers and Gaelic footballers - and indeed their fans - speak of Croke Park as if it were sacred ground.
"Croker" is something of a hidden secret for tourists. If you can get a tickets, the chances are that you will be one of the few tourists there. The best time to get tickets is usually around May at the start of the season. To go and see a game of either hurling or football at Croke Park is to sample a unique slice of Irish life.
While you're there, visit the GAA museum and for a tour of the grand stadium.
