Rapidly being completed in time for the World Rugby Cup competition to be held in Cardiff, the Welsh capital, during the 1999-2000 season, is the Millennium Stadium. The new 75,000 seat, all-weather stadium will replace the world famous Arms Park to become the world's largest arena with a retractable roof. It will also contain a rugby museum, a riverside walk, a public plaza and will be suitable for all sporting events and concerts.
