This stadium is home to FC Zurich and was used for three matches in the Euro 2008 tournament. To avoid dwarfing its surroundings, this massive structure was sunk into the ground. The excavated material was sifted on site to extract the local gravel, which was then used in the concrete. The most remarkable feature of the stadium is the sweeping roof. It is held aloft by 31 pairs of raked columns (formed with Corten or rusting steel) such that it almost seems to float. The soffit of the roof is clad with timber slats. Sheets of Corten are also used to form the perimeter fence. The capacity is 25.000 for football matches, 30.000 for athletics and 50.000 for concerts.
