 German stadiums such as the AWD-Arena, Commerzbank-Arena, Gottlieb-Daimler-Stadion, RheinEnergieStadion, AOL Arena, and Zentralstadion also underwent reconstruction/renovation by removing the running track to become football-only venues; several of these projects were done in preparation for the 2006 FIFA World Cup.A different take on the multipurpose concept can be seen in the Saitama Super Arena in Japan and Paris La Défense Arena in the inner suburbs of Paris.Both venues are similar to the Carrier Dome in that they are fully enclosed stadiums (though with fixed roofs instead of the Carrier Dome's original air-supported roof) that can accommodate field and indoor court sports.
