The National Stadium (Polish: Stadion Narodowy) football stadium in Warsaw, Poland, on the site of the former 10th-Anniversary Stadium.
The new stadium has a seating capacity of 58,145. Its construction started in 2008 and finished in November 2011. The stadium has a unique retractable PVC roof which unfolds from a nest on a needle suspended above the centre of the pitch. 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. It is expected that Legia Warszawa or Polonia Warszawa will choose to use the National Stadium for their most prestigious matches.
Along with the stadium the plans include constructing a general purpose indoor sports arena with places for 20,000 spectators, an Olympic-size swimming pool for 4,000 spectators, an aquatic park, hotel, conference center, as well as catering and service facilities. The construction will be followed by a complete refurbishment of the nearby Warsaw Stadium railway station and the opening of a subway station and a segment of the second line of the Warsaw Metro linking the area with the city center. The grounds are owned by the national government, thus the investment will be financed by it, rather than the city of Warsaw.
