This fine Baroque building, built in 1754-1756, now houses the Department of Contemporary Art (Oddziału Sztuki Współczesnej), a relatively quiet annexe of the Gdańsk National Museum, showcasing a fine overview of 20C Polish art. The collection includes works by Henryk Stażewski (1894-1988), leader of the Blok movement. Next door, in what used to be the abbey granary, is the Ethnographic Museum.
