Tour du Crédit Lyonnais

This guide to the Tour du Crédit Lyonnais starts on marshy ground that flooded for centuries until stone embankments finally dried it out in 1772. It follows the 1974 construction crew who drove foundations twenty-six meters down into that old swamp, and architect Araldo Cossutta, bound by an unusual rule tied to the Fourvière hilltop across the river. Stand at the tower's base and look across the water toward the basilica on the hill.
