Further examples of international Expressionist architecture are: the P.L.Takstraat Housing Estate in Amsterdam by Piet Kramer (red brick), the Goetheanum in Dornach by Rudolf Steiner (grey concrete) and the Casa Milà in Barcelona by Antoni Gaudi (grey stone).
Today Dornach is famous for the Goetheanum and is home to the international headquarters of the Anthroposophical movement founded by Rudolf Steiner.
