In August of 2008 I visited the Grand Arch (Grande Arche), la Defense, Paris, France with the intention of getting some nice photographs of the cityscape from the roof. However when I reached the top floor I was surprised to find a computer museum there. It was something totally unexpected and probably ended up spending quite some time just looking around at all the old machines. What was more surprising still was the fact that I have used quite a few of them in the past, so it was very much a trip down memory lane. If you are interested in computing and happen to be in Paris then this is one location you will certainly have to visit.
