The Mánes Association of Fine Artists (Czech: Spolek výtvarných umělců Mánes or S.V.U.; commonly abbreviated as Manes) was an artists' association and exhibition society founded in 1887 in Prague and named after painter Josef Mánes. The Manes was significant for its international exhibitions before and after World War I that encouraged interaction between Czech artists and the foreign avant-garde. It played an important role in the development of Czech Cubism and Rondocubism. Between 1928 and 1930, Manes built a complex with a restaurant, club, showroom and offices at the site of the Štítkovský Mill and water tower on the Vltava. The architect of the 1928 Manes pavilion was member Otakar Novotný. The union was liquidated under the Communists and was revived after the Velvet Revolution in 1990. Its headquarters became the Diamond House in Prague, itself a landmark of cubist architecture. Source: Wikipedia (en)
