The National Technical Museum puts everything in one room at once. Aircraft hang on wires from the roof above locomotives on rails on the floor, and cars and motorcycles are parked along balconies on three levels, so you look down onto a wing and across at a radiator. The hall is steel-framed and glazed, five storeys high, and you take it in whole from the entrance before you have read a single label.
What fills it is the output of the industrial half of the Habsburg empire and of the country that followed: railways, the automobile trade, aircraft, machine tools. The building came late. Milan Babuška won the competition, work started in the autumn of 1938, and the museum was finished in 1942, under occupation. The design is pure 1930s — steel, glass, three tiers of balcony, no partitions — and it was drawn around the objects rather than the other way round.
