The National Stadium (Polish: Stadion Narodowy) football stadium under construction in Warsaw, Poland, on the site of the former stadium Stadion Dziesi ciolecia. The new stadium will have a seating capacity of 58,145. Its construction started in 2008 and is to finish in November 2011. The national stadium is due to host the opening match (a group match), remaining 2 group matches, a quarterfinal, and a semifinal of the UEFA Euro 2012 hosted jointly by Poland and Ukraine. The National Stadium will not be the new home of Legia Warszawa or Polonia Warszawa football clubs. However, it is expected that Legia and Polonia may choose to use the National Stadium for their most prestigious matches.
