Qatar World Cup organizers have released the design of their fourth stadium on the fourth anniversary of their 2022 bid success.
The Qatar Foundation stadium in the capital Doha is being designed to seat 40,000, with the capacity reduced to 25,000 after the tournament.
Organizers say the Spanish-designed stadium's ''geometrical patterns are designed to pay tribute to traditional Islamic architecture.'' It is set to be completed by 2018 and can stage matches up to the quarterfinals.
FIFA requires a minimum of eight stadiums and a maximum of 12 for the tournament.
Although Qatar's bid is still being scrutinized as part of a wider FIFA investigation into the December 2010 vote, organizers say five stadiums will be under construction by the end of the year.
