Cardiff's Millennium Stadium became the home of Wales Rugby Union upon its completion for the Rugby World Cup in 1999.
Built as a replacement for Cardiff Arms Park, which still stands close by, at a cost of £130million, the Millennium Stadium has a capacity of over 74,500 and boasts a retractable roof.
The first game to be played at the Millennium Stadium was in June 1999, with Wales beating South Africa 29-19 in front of a Test crowd of 29,000, despite the ground not yet being completed.
The stadium was at full capacity in time for the World Cup and Australia beat France 35-12 in front of 72,500 supporters to lift the trophy in November.
Despite being the third largest stadium used in the RBS 6 Nations it is only the second largest venue in the world with a fully retractable roof.
Its record attendance stands at 74,576 when Wales played Scotland during the 2008 RBS 6 Nations while the stadium also held the Heineken Cup final in 2002, 2006, 2008 and 2011.
However, none of those four finals has seen a Welsh side life the trophy, with Leicester Tigers triumphing in 2002, before Munster twice and Leinster in 2011.
And most recently the Millennium Stadium was the scene of Wales' triumph in the 2013 RBS 6 Nations, as they beat England 30-3 on the final weekend to deny Stuart Lancaster's side a Grand Slam and claim he trophy for themselves.
Whether you do it as a day trip by bus, car or train, or whether you make a weekend of it, Cardiff is a RBS 6 Nations venue with a character all of its own.
It's the raw rugby atmosphere that you come to Cardiff for and on RBS 6 Nations Championship weekends you can literally eat, drink and sleep it on these streets.
Bustling, noisy, a little claustrophobic even, Cardiff on an international match day is quite an experience.
No rolling maul ever seen in the magnificent Millennium Stadium or its Cardiff Arms Park predecessor can match, for sheer heroic human endeavor, the crush at the city centre bars.
Yet Cardiff's centre, dominated to one side by the historic castle, is full of good places to eat and drink.
The shopping arcades, and market, are excellent and there are live music venues, art galleries and nightclubs.
