What should hosting an Olympic Games mean to a city? “Many Olympic cities have promised regeneration and few have delivered. From the Foro Italico in Rome to Homebush in Sydney, the world is littered with desultory, underpopulated Olympic zones that were once the subject of some planner’s proud boast. If the Olympics automatically gave its sites a boost, then Wembley, where the games were held in 1948, would be the hottest place in north London. This time, London has to mean it, and it has to deliver.”
