Although Ireland has never totally hosted the Rugby World Cup, select games from both the 1991 and 1999 World Cups were played throughout venues in Ireland. Pool B in 1991 was mainly played in Ireland and Scotland, with two games at Lansdowne Road (involving Ireland) and one (Zimbabwe v Japan) played at Ravenhill, Belfast. A quarter-final and a semi-final were also hosted by Dublin. A similar system was used in 1999, though in addition to Lansdowne and Ravenhill, Thomond Park was also a venue.
