Athens’ Olympic stadium, designed by Santiago Calatrava, has been a big hit, breaking with a dismal Olympic tradition. “The Athens approach—making an architecturally bold, camera-ready stadium an Olympic focal point—is less an anomaly than a sign of things to come. In the past, many host cities simply added a few thousand new seats to the biggest stadium they had; others used the games as an excuse to build a new home for a local pro franchise, as Atlanta did for the Braves with the less-than-exciting Turner Field. But these days, every potential host city’s Olympic plan seems to include an attention-getting stadium designed by a well-known firm.”
