Another Andō Tadao masterpiece, this museum sits entirely underground, its cool concrete spaces lit only by natural light filtering from above. The result is a series of contemplative chambers that transform the art within. Monet's water-lily paintings glow in a white room that feels like being inside light itself. Walter De Maria's monumental sculptures occupy rooms of staggering geometric precision. James Turrell's installation alters your perception of space and colour. Outside, a garden created in the spirit of Monet's Giverny connects the artistic experience to the earth above.
