German-Swiss painter Paul Klee's work is perhaps some of the most recognizable and famous of all paintings from the first part of the 20th century. 

Transcending the zeitgeist of his age (surrealism, cubism, abstraction) Klee regularly combined various media into his works. His Writings on Form and Design Theory is considered one of the most important theoretical works on art ever written.

The center contains about 4,000 works by Klee including the famous Dame mit Sonnenschirm (Woman with Parasol), In den Häusern von St. Germain (Houses of St. Germain) and Tod und Feuer (Death and Fire). The building itself is outstanding.
