Olympic Stadiums That Now Serve Completely Different Purposes
20. Nagano’s M-Wave Arena (1998) – Now a Giant Ice Skating Rink & Exhibit Space

Original Purpose: Hosted speed skating events during the 1998 Winter Olympics in Nagano, Japan. New Purpose: Converted into a multipurpose ice skating rink and event space. Instead of letting the arena sit idle, Nagano repurposed it into a recreational ice rink open to the public. It also functions as a venue for trade shows, concerts, and local events, ensuring year-round activity while keeping its Olympic legacy alive.
