The National Stadium (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. Construction work was started on site in 2008. The first activity was to demolish the old stands of Stadion Dziesięciolecia. The cornerstone (foundation stone) and a time capsule were set during the ceremony held on 7 October 2009. The time capsule contained flags of Poland, the European Union and the city of Warsaw, newspapers of the day, coins, banknotes, and other artifacts.
On 1st December 2009 two workers were on a working platform being lifted by a crane to the height of 18 metres (59 ft) above ground. The suspension broke causing the platform to fall killing one worker instantly and the second died in a hospital a few hours later. Another fatal accident happened on 9th May 2011. A worker fell from the roof. Authorities are investigating circumstances of this accident. In 2009, the construction works were scheduled for completion by mid 2011. However, construction failures were revealed in late May 2011, which resulted in setting a new completion term for 29 November 2011. The stadium has now been cleared for use.
