This jagged building is the Musée des Confluences, built on a man-made peninsula in Lyon, France, at the point where the Rhône and Saône rivers converge. “The ground water is very high,” says Wolf Prix, principal architect of Austrian firm COOP HIMMELB(L)AU. “We had to drill about 500 piles into solid ground so it would be safe to build on.”
