This exhibition and conference centre (featured, by the way, in Jacques Tati's 1971 film Trafic ) is the largest such complex in the country. The building opened in 1961 and just keeps expanding for the car, fashion, horse-jumping and 50-odd other shows held here every year.
RAI stands for Rijwiel en Automobiel Industrie, the bicycle and auto trade association that owns much of the complex.
