In development for years, this museum inside the former Kino Światowid - a local landmark in social realist architecture, completed in 1957 - is dedicated to Polish history between the years 1944 and 1989, telling the story of everyday life during the country's communist era. Temporary exhibits occupy the ground floor (currently 'Parcel from America' until March 4th) and upper level ('In Opposition: Solidarity in Małopolska during Martial Law'), while the former cinema's cellars hold the intriguing exhibit 'Nuclear Threat: Shelters of Nowa Huta.' There are actually some 250 shelters beneath NH - enough to accommodate every resident in the district - and this is the largest in Kraków. Well-translated throughout, including an instructive film with English subtitles, here you'll learn about the very organised and intricate plan Poland had for dealing with a potential nuclear attack during the Cold War, and the role every citizen would play in such an event.If you're from the West, it's akin to mild culture shock, and the space itself is impressively vast. Within easy walking distance from Plac Centralny, if you've made the trip out to NH there's no reason not to make a stop here. Szpeje - a small shop inside selling genuine antiques from the PRL era - is an added bonus.
