Cardiff is expected to receive a £316m boost when the Millennium Stadium plays host to next year's Rugby World Cup - according to an economic impact study announced by England Rugby 2015 today.
The stadium will host eight games, including two of Wales’ pool matches and two quarter-finals.
Wales' two training bases for next year's Rugby World Cup have been announced.
The Vale Resort on the outskirts of Cardiff and London Irish RFC will be home to Warren Gatland's side during the competition.
Tournament organisers England 2015 have announced the 41 team bases across England and Wales that will host the 20 competing teams.
Gatland's squad, which reached the semi-finals of the competition in New Zealand three years ago, will spend their time between the two venues for the duration of their four pool encounters.
Wales will share the facilities with France.
Other training venues in Wales are the Celtic Manor Resort, near Newport, Cardiff Metropolitan University, Sports Wales National Centre, also in Cardiff, and Swansea University.
Try-outs for those wishing to be among the volunteers for the Rugby World Cup in 2015 are taking place today.
It's the fifth leg of the try-outs, which are aimed at finding 6,000 volunteers for the championship.
The Cardiff try-outs are a chance for potential members of 'The Pack' to find out more about RWC 2015 and take part in a 20 minute one-to-one interview.
It's been confirmed that Wales will play two of their Rugby World Cup group games in front of a home crowd in Cardiff in 2015.
The Millennium Stadium will host eight games in total, including two quarter finals. The tournament is being hosted by England.
