While in exile in the United States during the years of the Communist regime, Jan and Meda Mládek assembled a large collection of 20C Czech art, supporting young artists persecuted by the regime. This museum presents a fine collection of works by living artists. There are rooms devoted to two major 20C Czech artists: sculptor Otto Gutfreund (1889-1927) and painter Frantisek Kupka (1871-1957). Beautiful view from the terrace on the top floor.
