This museum is all about the history and importance of Gaelic sports in Ireland and the role of the Gaelic Athletic Association (GAA) as the stout defender of a proud cultural identity. It helps if you're a sporting enthusiast.
The twice-daily tours (except match days) of the impressive Croke Park stadium are excellent, and well worth the extra cost. Admission to the tour includes a museum visit.
The stadium's other attraction is the Skyline, a guided tour around Croke Park's roof.
