The Kampa Museum is located in the complex of Sova's mills at Malá Strana and it cherishes the art collection of Jan and Meda Mládek, who actively supported Czechoslovak non-conformist artists. It contains, among other things, the largest collection of works by one of the founders of modern abstract painting, František Kupka, and works by other important artists of the 20th century from what is known as Eastern Bloc.
