Go for the state collection's modern works and the contrast between art inside and the long dark façade outside. K20 has its own entrance and programme; K21, across the centre at Ständehaus, is a separate contemporary-art visit rather than another door into this museum.

The black granite frontage across Grabbeplatz.
