“The fundamental architectural idea of the Louisiana Museum is the co-conception of the architecture with art and nature. In 1958, architects Jørgen Bo and Wilhelm Wohlert were commissioned to design the museum taking as their point of departure the old patrician villa. Over the years they have been responsible for the ongoing expansion of the museum. From 1991 onwards they were joined by architect Claus Wohlert.”
