Great Strahov Stadium (Velký strahovský stadion), Prague

The massive Strahov Stadium, one of the world's largest sports facilities, has been utilized in the last decade as a concert venue more than a gaming space, though Sparta Prague Football Club does train here. Host to mega-concerts that feature celebrated bands like U2, The Rolling Stones, and Pink Floyd, the stadium gives concertgoers a panoramic view of the city below. Plans have been in the works to convert this slowly-decaying, communist-era stadium from a giant venue into a commercial area for restaurants, stores, and hotels.
