Opened in 1955 to commemorate Poland's greatest astronomer Nicolaus Copernicus - of whom a fine statue can be found outside - this is the country's oldest planetarium, which given the time period isn't necessarily a good thing. Located along the cracked pavements of Silesia Park, while charming in intent the actual building is a quite depressed, somewhat scrubby 23m concrete dome. The large auditorium now shows a new astrological show entitled "Structures of the Universe", although it is currently only available in Polish. There is also a working observatory with a 30cm Zeiss telescope, seismic observatory and weather station, we're reliably informed the full sky show can be arranged in English. If you dig 50s sci-fi, you'll get a kick out of this; otherwise this throwback may be a disappointment.
