“A successful Olympics is measured not just by the gold medal tallies, the firework displays that accompany the opening ceremonies or the receipts from the television rights and the sponsorship money, but most conspicuously by what it leaves behind. With its soaring roof rising out of the Yoyogi park, Kenzo Tange’s Olympic pool for the Tokyo Games is still a landmark 40 years after it was built. It served to mark Japan’s coming of age as a modern state after post-war reconstruction. And Frei Otto’s stadium in Munich – despite the horror of the assassination of the Israeli athletes at 1972 Olympics – is a magical structure. Its elegant tent-like roofs are so popular that there was an outcry when there was a move to demolish it. But in the case of Montreal, and now sadly Athens too, the Olympic legacy is mainly seen in the form of debt.”
