Museum of Civilizations of Europe and the Mediterranean in Marseille

You're standing at the Mucem, the Museum of European and Mediterranean Civilisations, right at the mouth of Marseille's old harbour. Take a good look at the building. It's basically a big square box, but what catches your eye is the dark lace wrapped around it. That isn't iron or stone. It's a shell of fibre-reinforced concrete, draped over the museum like a net. Architect Rudy Ricciotti designed it with Roland Carta, and he liked to say he built it from stone, water and wind.
