Tragically overlooked by far too many visitors to Warsaw (who can’t see past World War II and communism) this is a joy of a museum that showcases and highlights all that’s best about Poland’s cultural heritage. There are costumes, handicrafts, furniture, Polish inventions, art, photographs; most of it is beautifully presented in what is a superb building.The museum is one of the city’s most active, putting on all sorts of temporary exhibitions (the current one is "Around the Table" (Wokół stołu) and viewable till June) plus they organise hands-on events and workshops. Directors of Warsaw’s other museums might want to come and take notes. Just brilliant, and unquestionably essential. A major renovation was recently completed and the new permanent exhibits "Ordinary Extraordinary" and "Time to Celebrate Polish and European Folk Culture" can be explored.
