Wales at the Rugby World Cup

England was billed as the main host of the second tournament in 1991, hosting the opening ceremony, and final, though the hosting duties were shared between all countries which competed in the Five Nations Championship. France hosted eight games, England and Wales each hosted seven, and Scotland and Ireland five. The National Stadium in Cardiff hosted the third place playoff, whilst all of Pool C's matches were played in Wales. Wales were scheduled to feature in this pool, and all three of their pool matches were hosted in the National Stadium. One game each was played at the club grounds of Pontypridd, Pontypool and Llanelli.

The following Welsh stadiums were used:

Millennium Stadium, Cardiff, where Wales play their home games

Wales was chosen by the International Rugby Board as the principal host for the 1999 event. The centrepiece venue of the tournament, hosting the opening ceremony and final was the Millennium Stadium, a new structure built on the site of the old National Stadium at Cardiff Arms Park at a cost of £126 million from private investment. An agreement was reached with the unions of all four rivals in the Five Nations Championship (England, France, Ireland and Scotland), so that, like 1991, the majority of the matches would take place outside the official host nation. In a unique tournament format there were five pools in the opening round. Each of the five unions competed in a separate pool, and acted as host for all of the matches within that pool. All Pool A games were held in Scotland, Pool B games in England, Pool C games in France and Pool E games in Ireland.

Wales hosted Pool D, also featuring Argentina, Samoa and Japan. Four of the pool games were at the Millennium Stadium, with one match each at Stradey Park, Llanelli's rugby stadium, and at The Racecourse, Wrexham, which usually featured Association Football.

Of eleven knock-out games, the Millennium Stadium only hosted three; Australia's defeat of Wales in the quarter-final stage, and the third place play-off and final. The other fixtures were played for at a variety of European venues.

The following Welsh stadiums were used:

City	Stadium	Capacity
Cardiff	Millennium Stadium	74,500
Wrexham	Racecourse Ground	15,500
Llanelli	Stradey Park	10,800

In a more public bidding process, France beat England to win the right to host the 2007 World Cup. The WRU supported the French bid, in accordance with an agreement between the nations over the 1999 cup.[7] As a result of that agreement, world cup rugby returned to the Millennium Stadium for three pool matches (including two featuring Wales), and a quarter-final.

Ironically, as France were unexpected runners-up to Argentina in their group, the hosts found themselves competing in this, the only knock-out match held outside of their borders. The game was one of the highlights of the tournament, notable for a large number of reasons, though largely for being New Zealand's earliest exit from a Rugby World Cup, after the New Zealand Herald ran the hubristic headline 'France pose absolutely no threat to All Blacks'.[8] The French squad's reply to the Haka, where the squad dressed in red, white and blue shirts, drew some attention, with a number of images of Sebastien Chabal's stony face appearing in the media the following day.[9] Several controversial decisions by referee Wayne Barnes,[10] provoked death threats from some fans.[11] Statistical analysis by New Zealand company Verusco showed the match's playing time, that is time the ball is in play, was the longest of any of the 1,500 games they had ever recorded.[12]

In 2009 England were awarded the rights to stage the 2015 tournament. Owing to the proximity of Cardiff, the RFU made it clear that they intended to use the Millennium Stadium as part of its bid,[13] despite initial reluctance from the IRB for multiple hosting nations.[14] The Millennium Stadium hosted eight games in the tournament, more than in any previous world cup. These include two quarter-finals. This made Cardiff the only venue hosting knock-out matches with the exception of England's national stadium, Twickenham, as well as the venue with the second highest number of games. As Wales and England have were drawn in the same group, Wales only have home advantage for two of their games, against Uruguay and Fiji.

Cardiff used the world cup to promote tourism in the city,[15] with estimates that the games will add over £300 million to the local economy.[16] A 'Fan Zone' has been created within the grounds of Cardiff Arms Park with a large screen, for enjoying match days.[17] Cardiff Council has commissioned an art installation to mark the tournament, grafting a rugby ball to the prominent Cardiff Castle, to make it appear the ball has smashed straight through the wall.[18] This is similar to a publicity stunt from the 2007 World Cup, where a rugby ball hung from the centre of the Eiffel Tower. No such other sculptures have been created in the other 2015 venue cities.
