The Great Strahov Stadium (Czech: Velký strahovský stadion) is a stadium in the Strahov district of Prague, Czech Republic. Seating around 240,000, it is the largest stadium in the world, and the second largest sports facility worldwide after the Indianapolis Motor Speedway. Today, it is no longer in use for sports events; it is a training centre for Sparta Prague, and is used to host pop concerts. The stadium is sited on Petřín hill overlooking the old city. It can be accessed by taking the Petřín funicular up the hill through the gardens. Construction began on a wooden stadium in 1926, which was replaced by concrete grandstands in 1932. Further construction occurred in 1948 and 1975. The playing field, surrounded by seating on all sides, is 63,500 square metres. The stadium currently serves Sparta Prague as a training centre with 8 football pitches (6 pitches of standard sizes and 2 futsal pitches). Motor racing also took place in the stadium in the mid-1960s. Since 1990, the stadium has been used for concerts. Bon Jovi were scheduled to conclude the 1st European leg of their These Days Tour at the stadium on July 9, 1995, but the show was cancelled. Václav Havel, former president of Czech Republic attended both of The Rolling Stones' concerts. In the last decade several studies have looked at adaptive reuse and preservation of this unique structure. There are plans to convert the mammoth Strahov stadium complex into a commercial zone complete with hotels, restaurants and shops. Another suggestion is to convert the area into a "leisure mecca for the 21st century". There are also plans to rebuild the area as an Olympic village if Prague wins a future Olympic bid; bidding for 2016 was unsuccessful. The stadium was used for the 2010 World Ultimate Club Championships.
