A vast collection dedicated to the history of everything technological inside the equally enormous Palace of Culture & Science, the only thing missing here is a map. Truly huge, and clearly laid out by somebody with a sadistic sense of humour, the scores of rooms scattered willy nilly and organised with what appears to be a contemptuous disregard for reason and logic, highlights include a cavalcade of impossible-looking motorbikes and aeroplanes, a room packed with 19th century musical boxes, historical cars like a 1936 Lux-Sport limousine chassis and a small exhibition celebrating space exploration that could do with some serious updating. Decorated with lace curtains and staffed by an army of sinister-looking old ladies, you won’t learn a thing no matter how hard you try, but it’s a strangely rewarding experience that really has to be seen to be believed.
