Cardiff Arms Park (), in central Cardiff, is among the world's most famous venues—being the scene of three Welsh Grand Slams in the 1970s (1971, 1976 and 1978) and six Five Nations titles in nine years—and was the venue for Wales' games in the 1991 Rugby World Cup. The Arms Park has a sporting history dating back to at least the 1850s, when Cardiff Cricket Club (formed 1819) relocated to the site. The ground was donated to Cardiff CC in 1867 by the Marquess of Bute. Cardiff Cricket Club shared the ground with Cardiff Rugby Football Club (founded 1876) —forming Cardiff Athletic Club between them—until 1966, when the cricket section moved to Sophia Gardens. Cardiff Athletic Club and the Welsh Rugby Union established two stadia on the site—Cardiff RFC played at their stadium at the northern end of the site, and the Wales national rugby union team played international matches at the National Stadium, Cardiff Arms Park, which opened in 1970. The National Stadium was replaced by the 74,500 capacity Millennium Stadium () in 1999—in time for the 1999 Rugby World Cup—and is home stadium to the Wales national rugby and football teams for international matches. In addition to Wales' Six Nations Championship and other international games, the Principality Stadium held four matches in the 2007 Rugby World Cup and six FA Cup finals (from the 2001–02 to 2005–06 seasons) while Wembley Stadium was being rebuilt.
