Catch a hurling or Gaelic football game at this 82,300 capacity, state-of-the-art stadium. These sports are uniquely Irish. Hurling is listed in the Guinness Book of World Records as the fastest field sport, with the ball (called a sliotar) reaching speeds above 130 km/h. Gaelic football can best be described as a combination of soccer and rugby. To keep the sports "pure," it maintains an amateur status, with each parish in Ireland having a team — the inter-county games are generally extremely well-supported, so you may have difficulty getting tickets for the bigger matches. Tours of the GAA museum and the stadium are also available, including a chance to try your hand at the sports themselves. You can also walk across the roof of one of the biggest stadiums in Europe, which provides great views of the city's skyline.
