Leinster Rugby is one of the four professional provincial rugby union teams from the island of Ireland and the most successful Irish team domestically. They compete in the United Rugby Championship and the European Rugby Champions Cup. Leinster play their home games primarily at the RDS Arena, although larger games are played in the Aviva Stadium when the capacity of the RDS is insufficient. Before moving to the RDS in 2005, Leinster’s traditional home ground was Donnybrook Stadium, in Dublin 4. The province plays primarily in blue and the team crest features a harp within a rugby ball, the harp being taken from the flag of Leinster. Leinster turned professional along with its fellow Irish provinces in 1995 and has competed in the United Rugby Championship since it was founded in 2001, having previously competed in the annual Irish interprovincial championship.
