A $60 million pop-up Olympic stadium February 10, 2018 Pyeongchang’s Olympic stadium cost South Koreans $60 million dollars and will be used exactly four times. That’s by design. From Citylab. The 35,000-seat pentagonal Olympic Stadium is an extreme example of pop-up architecture, a mega-event venue with a planned lifespan shorter than the career of an aerial snowboarder. The stadium will be used four times in all—for the opening and closing ceremonies of the Winter Games and Paralympics. Then it’s slated to be torn down.With its simple structure and open roof, the temporary structure was designed with demolition in mind—a technique that has been employed before in previous Winter Olympics in Albertville, France, in 1992. Given the sub-freezing temperatures expected, the unheated and roofless facility is perhaps less than ideal.But the alternative—a more costly permanent structure—is probably an even worse idea, experts say. Pyeongchang is a rural outpost of around 45,000 people in one of the poorest areas of South Korea, a country where winter sports have a small following. If the stadium isn’t torn down, it would likely be fated to join a mighty herd of white elephants from Olympics past—infrastructure that has gone unused decades after the athletes went home, yet continue to drain public money in upkeep costs.
