Christian de Portzamparc (born 1944) is a French architect and urban planner known for his sculptural, dynamic designs that blend aesthetic expression with urban innovation. His notable works include the Cité de la Musique in Paris, the LVMH Tower in New York, and the Grand Théâtre de Casablanca. A pioneer in urban form and spatial fluidity, he developed the concept of "open blocks", reshaping modern city planning. Awarded the Pritzker Prize (1994), he remains a leading figure in contemporary architecture, creating projects that balance monumentality, transparency, and contextual sensitivity.
