The opening of Aviva Stadium in May 2010 ended the arrangement with the Gaelic Athletic Association (GAA) that allowed the all-Ireland governing body for rugby union, the Irish Rugby Football Union, to use the GAA's flagship stadium, Croke Park, for its international matches. This arrangement was made necessary by the 2007 closure and subsequent demolition of Ireland's traditional home at Lansdowne Road; Aviva Stadium was built on the former Lansdowne Road site. During this construction, Croke Park was the largest of the Six Nations grounds, with a capacity of 82,300.
