Masterpieces from the Museum Berggruen

Heinz Berggruen fled the Nazis before the war and built, from nothing, one of the finest private art collections of the 20th century. This exhibition brings a slice of it back across the Channel: Matisse, Picasso and Klee at the height of their powers, rarely lent and rarely seen together outside Berlin. A once-in-a-generation loan, seen here by so few.
