In this musem the city honours its famous son, who fled the Nazis for the US in 1933. His abstract works combine bold use of colour with geometric forms. Presented in a starkly minimalist space are examples from Albers' key series 'Homage to the Square', as well as early lithographs from the Bottrop period. From Bottrop Hauptbahnhof take bus SB16 to Im Stadtgarten.
