Located in a former Franciscan monastery, the National Museum is a work of art itself with vaulted ceilings and a large staircase that houses an impressive collection of equally beautiful objects, which hardly seem to deserve the unflattering description of being simply 'old art.' Here you'll find paintings showing pre-destruction Gdańsk and its wealthy residents, as well as the work of Dutch artists in another room. The main draw, however, is Hans Memling’s highly detailed triptych The Final Judgment, which was returned to Gdańsk by the Russians in 1956 after a circuitous journey through the hands of Napoleonic troops and Nazis.
